I've recently got one Airbag sus a pain in the arse, I've swapped mine to springs already.

IMO the problems with the car is that they are too complicated, to many check systems which fail on a sensor out of range. Once you fix it it need reset lights turned off everytime time is doesn't check and think oh it fixed and head gasket problems on them too.

Mine has been converted to multi point LPG which is better than the single point, And it has had the heads rebuilt.

The worst problem is trying to buy 1 the owners are fuckers, they know the car has a problem but there are so many things to check they hope you won't find it

Goodluck
