Yeah, agreed.
Personally i'd go for the MK5 instead of the MK4, same back end but a much nicer front end.
I also wouldn't go for the basic model, i'd get one with some nicer features, you'll really be pleased you did if you do. When your first thinking of getting a car, almost any seems a good idea at the time, but trust me, you'll be much happier in the long run if you spend just a little extra.
You can still get the MK5 with a small engine, bit newer car so less likely to go wrong, or have serious issues.
Same for the MK5, tons of parts around for these, they are hardly an expensive car either, in particular now this 'credit crunch' has took car prices down some.
Best of luck with your test on the day, just relax about it and think of it as any other lesson.
