Auto Appraiser Jason Phillips was privileged to inspect and ride along in one of the nicest rotissarie number's matching V code cars I've ever seen. It was a beautiful fall ride down this two track curvy hilly road in Maryland, slightly over the speed limit. Check out the nervous Toyota in front of us, that eventually pulls over and gets the hell out of the way! It's a number's matching, well executed frame off restoration. Be sure to check out the other cold start and walk around video. True muscle that was built to be driven! This car was inspected for a potential buyer. Do you need a car inspected? Call us, anywhere in the USA, 310 inspectors can go out and put their hands on your next potential dream car. 800-301-3886 or email us Thanks for watching.
