Cracking motors, to bare for my liking, commute a lot, so I opted for a white GTI-6 instead, had it year and half, came from a mk1 172, 6 is just leagues ahead in terms of involvment and feedback, much much better drivers car.
Heres mine:
Get yourself a thicker rear ARB, I've got 26/28mm iirc in mine at the back, hightens the rear wheel steer, you can really just chuck it around, handles awesome.
Oh and airbag light prob is connectors, quite common although not had it happen to mine. Hardly spent owt on it really, starter motor and goes through front ball joints but there cheap to replace and prob has summit to do with country lane blasts lol
