Re: ballpark figure - respray for 156
bodyshops are usually 22-25quid an hour trade to trade, as in insurance work, they book fairly standard times and their guys often complete in 75-80% of the time quoted, thus making the bodyshop more money.
(these facts and figures taken from a main dealer bodyshop I know who I can't name for obvious reasons)
I think you could throw 1200-1500 quid at it for a full respray at a quality bodyshop - thats trade price maybe more?
The magic in a bottle 2-pack is now pretty much extinct, with water based paints being what is typically used, some of the bigger players/main dealer body shops have been on water based for some time/years, and got really good at using it, this is something to be aware of - find a body shop who has been using water basepaints for some time, the guys who have just gone over are struggling with flashng off times (being longer) and application techniques (runs, curtains etc.)
I know body shops who are good - in some work, but inconsistant, so for every good job comes a bad finish also.
For me, go main dealer or similar, that way you can scrutanise the car before accepting it and paying for it and get them tosort out any issues you are not happy with.
(I am not saying all else are no good (far from it) I used to use a 1-man band who was fantastic, but having been in the trade I know the inconsistancies and lazyness' of some body shops, and as you are asking for a recommendation, I take it you don't know a good body shop ou can trust?)
