Not a lot, it was just that my clio was in recently to have a rattle fixed. It went in twice and had about 30 miles put on it, (one time leaving the fuel warning light on, but it was very low on petrol when I took it in ), and no one said anything to me about driving it. Just wondered whether they should have mentioned something to me at least as a courtesy thats all. I realise they have to drive it to find the problem as most of the problems only occur when moving, so thats fine, just not keen on some mechanic ragging the car round!
