One more "guess what's under the car cover"... and I wasn't even able to guess until I saw the lug nuts

 

So my guess is 65 low dollar Mustang. Plain jane white one, nothing remarkable, just one of millions made.

Only remarkable now, because in 60 years, it hasn't been crashed, or left to rust, or been stolen, or sold out of the country. 

NOW that makes it remarkable just to be a nice old Mustang that's still hanging around, but has never been upgraded to some nice rims, or probably anything else.
