Took my car to JBS in chesterfield and they had it about 2 hours to dignose it. the diagnosis was they want it now for an entire day to check for wiring faults etc. so 8 hours x £45 = £360 + VAT = 420 odd quid as well as any parts that might be needed. I bought the car 2 months ago and i reckon the chances of getting the place i bought it from to cough up are very slim. I did buy a 2 year warranty with the car BUT it doesnt cover electrics.
