I was thinking of looking for a GTI as a second car, anyone have any info on what to look for? How reliable is the 1.8 turbo compared to the 6 cylinder? What are some common problems? Also if anyone could explain the MK 3 MK 4 and so on. I am not a mechanic so if I am looking at major headaches and/or high maintanance cost,please let me know that too. I was looking at the 99 to 04 version. Thanks
