Took mine in for a 'free' bonnet catch and ended up leaving with a bill for 450 quid!!
They did a 25 point check or something and found every expensive thing they could that needed replacing :S. Didnt really have much choice other than to have it done.
So watch out when you take yours in.
lol, if it didnt need doing, or you were not happy with the price then why did you have it done ?
