Does yours have a Hayward and Scott exhaust? I was going to get one of those, before I got fined £500 in France for speeding.
Was tempted by a prospeed as well, but it doesn't look as nice as a Hayward and Scott. £480 is a lot of money though for a back box.
Did you get a good price for your service? Can't believe they had your car all day. I took mine to Andy @ GDI for its 12 and watched him do it for an hour, was offered a cup of tea, then simply had a nice drive back from Cambridgshire to Nottingham. Will definately be going back for its 24.
