The W124 AMG exhaust came in 2 flavors - old logo (pre-merger) with oval tips and the ////AMG logo with rectangular tips. Forget about trying to find a pre-merger logo W124 exhaust. I bought the only two I have ever seen on Japan Yahoo and that was years ago for Jono and one of his customers.
Here is an auction for the later AMG exhaust
★★★ご覧頂ありがとうございます★★★ 商品説明 W124 500E AMG リアマフラーです。 500Eより取り外し、大事に保管しておりました。 今ではかなり希少なAMGマフラーになります。 中古では、今では中々出てこない商品です。 外観ですが、シルバーに色塗りされております。 スクエアー部分は比較的綺麗ですが、裏にスリキズが御座います。 本国でも中々手に入らないと思います。 こちらの商品の価値をお解かりの方!是非どうぞ! 商品状態は、画像にてご確認下さいませ。 その他、124関連パーツ出品中! 画像撮

Price is about $1,300 (divide by 100 or so). Total cost with fees and shipping figure $2,000 all in. I would expect the P/N on this exhaust to start with "HWA" vs a stock 124 part #. Not an expert on post-merger AMG exhausts.
The 3-piece OZ Racing wheels are available regularly from different sources - eBay, forum members, Japan Yahoo. Can go with all four wheels the same ET28 8.5x17 or staggered 8.5 fronts and 10x17 rears ET18. You have to be extremely careful about cracks in the lug holes on these wheels.
