Hi I just wanted to introduce myself. My name's Mark and I live in South Lakeland (NW) I'm 24 and after driving diesels and other slow cars all my life i've decided to go for something a little more poky and so I've just bought my first ever Golf, a Mk2 16v

It cost me 400 notes so it was quite cheap however it does have a few problems, it leaks from somewhere. the whole floor panel seems to be wet, this includes passenger side, drivers side, and two back panels (all the soundproofing is wrecked so i've had to remove it all for now), i've checked the roof but theres nothing. Also the doorseals/windows seem to be ok so I'm a little baffled. Could it be leaking in from the front under the bonnet somewhere?
Another thing i'm finding is that it doesn't handle quite as well as i would have expected. It seems to be very tail happy and quite unpredictable, sometimes i'll lose the front slightly and sometimes the back will just swing out, granted i'm just getting use to it but as with all cars i like to test the boundaries and throw them about a little to get a feel for the handling. It's just that I hardly pushed the car and the back was away, is this common?
It has been lowered 40mm but unfortunately it has no service history so i don't know much about it. It has quite an oil leak that seems to be leaking from around the dipstick area other than that it starts well, sounds nice, and goes really fast. I'm really impressed and have started to fall in love with it already, it never fails to make me smile when i put my foot down.
When I get some photos I'll stick them on but in the meantime I was wondering if anybody could help with the issues above as I don't know may way around golfs whatsoever and think I'm going to have to do a lot of learning.
Anyway ciao for now
regards
Mark
