I'll definitely getting new shocks and springs. I want to lower it bit. I've been reading about the cooling system and I'll probably do a over haul of that if I get it. Another thing I'm worried about is the rear sub-frame I've read so much about. I'll try to get it checked out from RMP or a local shop before I make the purchase though.
I don't mind spending money to maintain the car but if the car is known for major problems then I'd rather avoid it.
I was checking if there was anything in particular I should know about the E46.
The only two thing so far I've found are the rear-subframe tears, the cooling system, and the Vanos seals. The Vanos seals have been replaced already so that's a good sign.
