Sold this to buy my E90. 98 Cobra with almost 600whp and fully modded suspension, I could pretty much outrun 95% of cars on the road in a straight line and around a corner. I don't regret it whatsoever. Every car I've owned has been fast with a stiff suspension. I've had my BMW for 2 days and everything about it makes me so happy that I switched up. Build quality is amazing and the car's power and handling is great for all road situations, even stock. Driving 80 miles a day for work is going to be a dream now.
I don't think I'll do any heavy modding anytime soon, but I can only imagine how awesome a 335 could be with 100 more hp and coilovers.
