This looks to me like something resembling a 65 mustang.

If you look at some 65 mustangs they only had a driver side wing mirror as that was the law back then. The wider rear tire also makes a lot of sense, as it's a RWD car that needs wider rear tires to support the traction.

If the car in the photo is a 65 mustang, I think the AI did pretty good.

This is like using a 6-fingered person in an AI imaging advert.
