£300 is well steep! do they undo your belt and pull your trousers down also or that an additional cost??

got mine done for free. well a bacon & cheese melt & a pint of coke! so i suppose it cost me £5.95!
call around mate! if ur ok wiv car maintenance possibly DIY then get the trackin sorted by the garage... see the "how to guides..." id say £50 for springs, £100 labour... £150... thats half your original quote!!!!!!

concider the time it takes to do the job mine was done in 1 1/2 hours!! its not time sonsuming to lower a sax, simple as 123 if all goes to plan!
