well here goes, sort of got fed up recently with the car, exhaust rattling, overheating, squeky brakes,rear diff leaking... and not holding owt above 7psi, oh and it acts like its got a flat battery sometimes tho the battery and starter and alternator have been tested... any ideas?

how much for a decnt exhaust, suppliers?
springs?

sorry for the rant but this car is truing into a money pit and my partner hates it!
