I bought this car October 2023 from a good friend of mine who had owned it for 20 years. Originally I bought it planning to V8 swap, I am still considering it, but I also think building it as the "ultimate M roadster" would be good too. As it is equipped with the S54 engine I have had thoughts of a CSL intake, headers, exhaust, 6 speed ZF transmission and a 3.46 differential...

Shortly after the VANOS work I decided to fix the sagging exhaust. The driver's side has sagged since I bought the car and after looking, it ended up being a really simple fix - the nut for the hanger fell off, the bolt was still there so I just found a nut that fit and re-installed it. Then polished the tips a bit because I was there.
