So I just bought his car today. Kind of an impulse buy, but from everyone I talked to it was a good deal. It's in amazing condition for being a 90' and having 150,000 miles. I paid $1800 for it, it has no mechanical issue and runs well and like I said is in amazing condition. Did I get a decent deal? Regardless, the car is mine. So I have a few questions. What kind of problems should I look out for? What things will I come to love? What kind of aftermarket parts are available and should I even bother with them? I know very little about BMW's but assume they don't need anything aftermarket to drive amazing. Thanks for any help, I'm extremely excited to own this car and can't wait to start workin on it and driving it.
