i had a load of cars on my watch list. I have a mk1 golf, 2 mk1 cabriolets, some mk2 gtis and some mk3 gtis as well as a corrado! lol.
I ended up buying a mk3 golf cabriolet with 129k on the clock, no history though :-(
I think your right about mk1/2 golfs now, you should look for body condition rather than engine mileage.
I also have in the back of my head what if i need to sell it, most people wouldnt touch a car with higher than 150k unless its to a fellow vw fan.
