Looking to get some reviews from members who have purchased seat kits from either or both German Auto Tops (GAT) or GAHH automotive for their .036. Is one truly better than the other?

Ouch. That could mean no more half-price leathers from GAT. The GAAH prices normally resulted in a scream of "GAAAAHHH!". ±$2500 for a pair of fronts is nuts.I learned courtesy of MMWA in Australia today, that GAHH has bought out GAT as of January 4 of this year. So evidently they are operating GAT, but it can be expected to fold into GAHH in the future.
This depends on the year and model. Standard 124's do indeed have the heaters sewn into the back side of the leather covers, and these must be extracted and re-sewn into the new leathers. @LWB250 just did this on an .034 recently. However, W124/S124 (sedan/wagon) Sportline seats and all E500E seats have the side/bolster heating elements glued to the "horsehair" pads, they are not attached to the leathers. The center heating elements are loose and slide into fabric 'pockets' on the leather. Completely different design vs standard/non-Sportline seats.... he had to disassemble the original covers so he can get the heating elements out and send them in advance to have them incorporated in the new seat covers when they were sewn. For that reason I am trying to get some in advance from seats in the JY and keep my original covers intact, just in case. You may want to consider that if you have heated seats.

				Dave, is there an easy way to individually test the elements before installation? I'll be using new seat bottoms with elements but re using the seat back elements (if indeed there are elements in the seat backs) I'd like to know before i send them the seat back elements / or covers.Ouch.

Note that on almost every single 124 that I've had with heated seats, at least one element is defective; typically driver seat, typically outer bolsters on bottom and/or backrest. There are 3 separate elements on the bottom, 3 in the backrest, on each side... 12 total per car. Due to the series/parallel wiring, if either left OR right bolster element is dead, the good one on the opposite side will not heat. All the elements are NLA, as are the 036/Sportline pads/cushions.

Check them with an ohmmeter. The individual "panels" have connectors between them, so you can separate the circuits and check the resistance. Depending on the size of the panel they'll range from maybe 5 ohms to 10 ohms, I believe.Dave, is there an easy way to individually test the elements before installation?

I'm getting very close to ordering new so I'll let everyone know the results.

Looks like prices are pretty comparable right now for the .036/sportline style sets.Ouch. That could mean no more half-price leathers from GAT. The GAAH prices normally resulted in a scream of "GAAAAHHH!". ±$2500 for a pair of fronts is nuts.

Dan is correct. Each individual element should be single-digit ohms. I want to say between 3 and 6 ohms, approximately. I can measure some i fyou want exact numbers. Bad elements will usually be open (infinite resistance) due to a broken wire somewhere inside the foam, but a high resistance reading (dozens/hundreds of ohms, or higher) also indicates a bad element.Check them with an ohmmeter. The individual "panels" have connectors between them, so you can separate the circuits and check the resistance. Depending on the size of the panel they'll range from maybe 5 ohms to 10 ohms, I believe.
Interesting... the prices are getting closer. Below is pricing from 2013 (at this link) when GAAH was double the GAT cost:Looks like prices are pretty comparable right now for the .036/sportline style sets.
$1075 for fronts from GAT with headrests
$1360 from GAHH on sale.
free shipping for both.
I actually may have gone a bit overboard and bought GAHH seat coverings for all four seats, extra leather for armrest/seat backs, and then I got the carpet kits too (even recarpeting the doors). I stripped the car down myself and had a local upholstery shop do the work (including sending the seat to GAHH to have heating element sewn in properly). I spent about $9k for everything. When I got everything back together, it really was like having a new car (including the new car smell). I redid all the wood around the same time tooI think member @bclifton used Gahh for his front seats on his former 560SEC. I think he was pleased with the results, but I'll let him comment.
One thing that caught my eye is that he had to disassemble the original covers so he can get the heating elements out and send them in advance to have them incorporated in the new seat covers when they were sewn. For that reason I am trying to get some in advance from seats in the JY and keep my original covers intact, just in case. You may want to consider that if you have heated seats.
@sheward, is that just labor, total job out the door, or something else? Maybe shops get a wholesale discount? Just trying to get a sense of what a regional upholstery shop might tell me. At most I only need fronts. Or should I say “want” fronts. I’ve been trying to stay away from restoring this car, but I’ve also been steadily losing that battle. The more I keep it the more I want to do just because... after 30 years you feel like all that stuff is “due” anyway. Yet you have those who go for the “unrestored” look and feel.I just heard back. $1350. for the front covers. $1275. for the rear covers. $150. a pair for headrests.
I'll be ordering front seats Monday.

Swap driver/passenger backrests to get the pilot seat fully heated. Then put any modified heaters on the passenger side, where (presumably) they would get less use.I have two non working heater elements. Both drivers backrest bolsters. Not suprised since the outside bolster sports a 3 inch hole in the cover with heater wires visible. I may decide to fashion new elements from the old seat bottom bolsters. All the good elements were showing 6 to 7 ohms.

I'm hesitant to remove the seat back pad from the frame due to the worry of cracking the old horsehair pad. There is a flap at the bottom of the pad that needs to unfold 180 degrees to remove it.
			
		
		
			
		
		
			
		
		
			
		
		
			
		
		
			
		
		
			
		
		
			
		
		
			
		
		Yes - the wire started to fracture before it broke, and the high resistance at that point caused a localized hot spot, which burned a small hole.Dave are you thinking the wire caused the burn?

That is a great price. If you don't mind, I would like to know how the leather piece for the center armrest (later style?) turns out.I just placed my order with GAHH. Their price is slightly more than I could have paid through Buds Benz locally however I thought the difference was worth talking with the folks who will make them directly. Jack Dekirmendjian, VP Sales and Marketing was very knowledgeable and sent out two samples of leather, crème beige and parchment to be sure I was getting what I wanted. I'm paying about $1,500 for two front covers and $160 for two headrest covers. I also ordered an armrest cover for $75. They have these for both early solid armrests as well as the later two piece versions. Shipping is free. The grain on the samples is a bit heavier than OEM, which is nearly smooth, but beautiful to my eye. Jack was aware and theorized that the original leather may have smoothed over time. Certainly plausible but I'm guessing the OEM leather was smoother. Regardless, the difference is slight and I'm not concerned. If someone is recovering for a 100 point concours judgement they will have to spend some time searching further and then hope that GAHH will use their leather. I was told it will take about 3 weeks for them to ship.

Drew, I've visited GAHH and they are a very solid and reputable operation. I also have had their skins on both my former 560SL and my 560SEC. I will make these observations:I just placed my order with GAHH.

When I had my GAHH front covers installed, my upholsterer swore up and down that replacing the leather at the later-style armrest was going to end up look crappy, and so I had my center armrest re-dyed.
My covered upholstery 560SEC center armrest turned out just fine (it's mushroom). Same for my former 560SL (which was saddle).Unless you remove the old flip-top armrest leather and replace it, the end result will not be aesthetically pleasing... this may be an involved job. You may want to re-cover a donor flip-top armrest just in case, that way you keep the original unmolested.

Who is GAT/GAHH?If you mean the seat leather covers... you're going to be waiting a long time for a factory set to appear. I've never even seen OE factory leathers for a 124. Contact GAT/GAHH in SoCal for the C43 leathers.
So basically you order the leather pieces(kit) for a specific seat and you find a place to stich it together for you? Am I right?Those are 2 different companies specializing in leather covers. Details here:

No, you show them what your seats look like, send color samples if you are worried about it being an exact match, and they create the covers for you - ready to install. Contact them with a photo of your seats and ask for a quote.So basically you order the leather pieces(kit) for a specific seat and you find a place to stich it together for you? Am I right?
I highly doubt theyll have factory champagne color c43 leather. Its quite unique...i havent seen it in any other mercedes.
					
				
Thanks! GAHH, but, frankly I think sooooo much of the impression of quality is dependent on the installer ….. stretching, steaming, smoothing, etc. Upholstery work is such an art form……@jlla which ones did you buy? They look crispy and clean like new linen sheets.
I was very impressed
