I'm thinking about pulling the trigger on a 2003 s55 with 58K miles. Spark plugs and engine mounts replaced, transmission seals replaced, drive belt replaced, fuel filter replaced, all of this done prior to 37520 miles in 2009. AC evaperator temperature sensor replaced, valve cover gasket replaced and suspension system checked at 44k. Its a 1 owner. What do you guys think its worth......Thanks

If I was you.

I would buy a CPO car and save myself from future headache.

An old car is an old car.
