I specifically made sure I didnt get a sunroof on my GTI, I had previous cars with a sunroof, my 84 scirocco and 87 quantum had one, I did use them occasionally, but they did start leaking due to change. Same with the 1997 beater integra i had, I had to clean the drain plugs that were causing leaking in the trunk due to being clogged. I'll give it 5-10 years before it starts leaking or something.
Sunroofs are nice, but not something I would pay extra for, and I havent missed it since. But I guess seeing as many posted liking sunroofs, that explains why I had a hard time find a base 6spd non sunroof 4door gti.
