It sounds about right, depends on what issues were address while at the dealership. Check to see if the front lower control arms & if the strut mounts have been changed posibble under warranty. Mine havn't been changed yet in 40k, but others have had issues with them and had them changed before 15k. Other than that these cars are bullitt proff for the most, there are several that reported ZERO problems beyond 100k, others have made it to 200k+ with very little issues. If it was taken care of and taking for its normal maintenance then there should be no issues.
Others may chime in on their issues, but havn't had an big issues other than some mods that end up making trouble for me. Good luck in your search, ?color?
