FUJATIVE....  I have been the owner of a golf for the past 5 years and have had some problems with it, but overall im glad I have it....I would recommend not buying a mk3 gti if it isnt a VR6, because you're wasting your money.... mk3's (1994-1998.5) gti's come with 2 engine options a 2.0L 8Valve, and a VR6....the VR6 is fast and ballsy, and there are plenty of mods you can do.... the 2.0 GTI....is a waste because you'll be paying for the "GTI" logo on your car and a few interior options like nicer seats...and your insurance will be higher than if you get a Golf GL for example, that comes stock with the 2.0.... if you're in canada, there is also an mk3 golf that comes with a 1.8 8valve...the golf CL...not as much power as the 2.0....but very reliable....
on that note, my car has 350,000km, and I blew it up the other day...but...I've got a new motor and its being installed....total cost is about $900installed ...so not very expensive......just watch out for the exhaust systems, they tend to shit the bed quick(especially if you have to pass an emissions test) Check all hoses and Belts....and make sure all the fluids look good and not filthy, or strange...hope that helps if you need any info about dubs, IM me... i know lots Peace
