We have had the car for 18 years, it was purchased as a lo mile used vehicle. Running a 454 CID big block it has performed very well and is good on gas. Originaly we had a 28 ft trailer to hall cross country, didn't even notice a pull or load on this chassis. My 350 cid truck boged down and was difficult to stop.
