Well, I got my mechanic to check it out. It was a complete dud! The engine mounts were worn down to nothing, the rear main seal was leaking, the power steering was pissing out fluid. The radiator was leaking, the transmission was on the way out etc. etc. I'd picked up on the oil leak (thought it was the rockers though), the dealer downplayed the steering and auto problems when we went back on Friday after he was meant to have fixed them, which is why I got me mechanic to give her the once over before making the final decision. Good thing we did!
