I have owned my Lincoln Mark IV for 15 years. Its all original except I replaced the vinyl roof and upgraded the ignition system and carburetor to make it more reliable and perform better. I also replaced the tires last year.
The interior is red cloth and is completely original including the carpet and looks like new. Everything still works, as it should, including the A/C climate control, the cruise control and clock. The car rides and runs awesome and draws attention everywhere.
The car came from San Diego, CA. I acquired it with 101,000 miles on it, from a relative of the original owner. Clearly this car spent a pampered life in Southern California and it shows everywhere you look, even under the hood.
