But be warned, as mentioned above these are specialist cars and 'when' things go wrong, it will cost!
As I've said many times there's 3 levels to parts prices on the VX
1 Common to other GM cars = V cheap
2 Common to the Elise family = reasonable but vauxhall will try to charge a fortune for them.
3 Specifc to the VX = £££££££££
As for cost as said above the cars are very tightly packaged to to fix any thing requires the removal of lots of body work which mount up the labour cost if your paying a garage. Also if you fix anything on the suspension then it normally means the geo needs to be redone adding an hour or so.
