Help! Decent garages in Aberdeen

[fatbutt]

Anyone know of any decent, honest and more importantly, CHEAP garages in Aberdeen? I need some work to be done on an oldish Merc (2001) and the dealers is doing the usual multiple of £500 approach.

Thanks Gents - the nearest to the office is the service station in Westhill but they seem to be very pricy at the mo.
