I have a couple of questions which I know most of you BMW owners could help:1. The facelifted 318i version is from 2003 onwards right? If I were to get a used one, buying a 2003 and above car is fine?2. I heard that the engine can sometimes leak engine oil after "x" amount of years. Is it a known problem on the E46?3. Is it worth it to buy a used CKD or recond Japan/UK spec 318i?
