Hi MkII Golf GTi...no question. Next to the classic scoobie that I now own, it's been one of the best and most reliable cars i've ever had....I had mine for 7 years with no major failures to report. Good thing is that you'll pick up a belter for much less than 3K too!
Parts are easy to get, they are easy to work on, don't rot too bad and return a decent mpg when you don't cane them.
Good luck with the hunt.
Cheers.
