Hi, I looked at a 172 cup today with 15k miles. Looks a lovely car so i put a deposit on it subject to a couple of things: 1: theres a thin spread of oil all over the top of the rocker cover, it was quite dirty so i am guessing its old oil. is this normal or do they leak abit or is there a major problem with the car?! its also missing a couple of services, i guess cause its so low mileage (53 plate) the previous owner didnt worry to much about it. its had an 18000 mile service done at 11000 miles. has it missed anything major? The car felt tight to drive and didnt rattle at all compared to a 182 cup i drove the week before with the same mileage. any advice would be much appreciated. Thanks
