I like to think I am a unique individual but then you read some smart marketing report or one of @Jlaa astute observations about automotive nostalgia (below) and realize you are part of the herd

When I was 19, in 1989, my Dad purchased a used 1981 BMW 320i. I loved this car and I tried my best to maintain it but I just did not yet have the skills I now possess. It basically kicked my ass where I took it to the dealer of all places for repair several times. This hollowed out my wallet every time but I had a great well paying engineering internship at the time and was living large.

I am just pissed in retrospect that I was never able to "master" this car and make it run like a Swiss watch. So I keep toying with the idea of buying one, dropping a more modern early 90s 4 cylinder in the thing, and putting the BBS wheels on it, and living like a teenager again. I want to dominate this car as I regret how it toyed with me in my early years of wrenching. These cars are still relatively cheap as the unloved successor to the 2002 model. Basically doing what this guy did in his perfect restoration.
My worry is the car was great with rose colored nostalgia glasses on. Hence the need for more power. What I love about my E500 is I bought it with nostalgia in my heart based upon loving my Dad's 1987 300D, but then the car exceeding my expectations in so many ways. The E500 ending up being better than I imagined.

Around 40+ years of age is when some people are fortunate enough not only to look at one’s own teenager years with rose tinted glasses, but also be able to enjoy a station in life where one can start to act out one’s dreams that have been recurring through one’s “entire adult life.”
