wouldnt know what to tell ya, ive had a mk2 8v minter h reg 1 owner low milege all that crap but it was nothing compared with me new 1.8 20v (non turbo), ive test driven a load of mk3s and was gonna get one before this mk4 came up at the right price, i know every ones been on here slagging off mk3s but if your thinking of keepin it for a while id go for a mk3 there more modern lookin, a safer car, not that bad on insurance (mk2 have still got the car thief bad boy image), thats my opinion, i may get slagged off for tellin ya so but as a part time car dealer for resale values your gona get more for a mk3 in years to come than a mk2, even if ya tune it up wheels , exhaust, etc just keep all ya standard bits for when ya want to get rid it will be worth more standard than a boy racer mobile!, people like standard cars m8, its all down to personal taste how you wanna tune em and dress em, you get more in the future buy sellin ya bits and sellin the car standard than ya do sellin em max'd up! its not all about performance its about how ya drive em, yeah a mk3 2ltr 8v is only 115bhp and a mk2 16v is 136bhp but if youve got more bollocks than the bloke in the mk2 youre gonna have im, mk3 handlin aint up to a hot mk2 but for a few hundred quid you can sort that. Ive got a t reg mk4 1.8 20v (non turbo) its only 125 bhp standard yeah its not a turbo but hey , its only group 10 insurance! get that GROUP 10, cheaper than me mondeo that i changed it for, yeah its not pull ya face off performance but it looks good handles well and if ya time it right you can beat a lot of cars from the lightds! ( by the way i race susuki gsxr1100 drag bikes) alot of it is down to reaction times at the lights m8 not what your packin, yeah if your packin a 2.5ltr twin turbo jobbie gainst a 1.8 8v your gonna have a bit of bother but if you pitch a standard mk2/mk3 8v at the lights m8 its down to the driver not the car, so its up to you sorry to boe you with my opinion, but im sick of people slaggin mk3 golfs off, for the money you cant buy better, buy a mk3 over a mk2 that my opinion, there the better car for your money and cheaper to insure no matter what your age, or if ya can get more funds, try what ive just got a mk4 1.8 20v (non turbo) as its only group 10!!!!! less than a 1.8lx modeo!!!
hope this may help, the decision is yours, know what id choose, but go with your heart!
PS all volkswagen spares are cheap, dont think by buying a mk2 parts will be cheaper cause mk3 parts are just as cheap!
