I'd be interested in finding out who'd be recommended on this, in North London fairly often - when I bought mine, I drove 'straight in' into my driveway, only to slightly scrape the bottom of the bumper on the drive - learning very quickly that it's fair a bit lower than the focus I used to drive which means I now have to enter the drive at an angle (one wheel up, then the other - rather than straight in)
Anyway, by being a bit of an idiot, I took a few tiny little bits of paint off, so it needs sorting!
My cousin has been telling about a really good one in North London. The guy apparently works for dealers and top end cars, etc. Not had any experience myself though. can get the details tonight for you.
