Slightly late but wanted to introduce myself. I've always admired the z4m coupe from afar. I think it's got a quirky but beautiful shape and lines. I have an e46 m3 I track and it's a very fun car to drive. I also own an e30 and sold my 1971 2002 about a year ago. I was fortunate enough that the timing worked and I was able to purchase a coupe from a member here. The car needed the major maintenance done and tlc. So I did the rod bearings and vanos along with some other maintenance parts before really trying to drive it. I'm glad I did, the bearings were showing copper on all top bearings with less than 100k miles.
So far enjoying this car. I'm glad the wheels are interchangeable with my m3 so I threw my re30s. Also gave the car a good detail and paint correction. Hoping to take it to the track to learn it's dynamics at the limit compared to the m3. Fun car, I feel like James bond when I'm driving. Haha!
