Thanks!

We started by lightly wiping the seats down, Next we steamed them really good, then we gently cleaned them with a general purpose cleaner (Incredible Pink) to get any leftover dirt off and last we put on a vinyl /leather conditioner which is more or less just a spray wax , we let that dry and then hit them with a very soft boot brush. The seats were absolutely filthy but they look and feel brand new now. I think the windows might have been down for at least the last 10 years maybe longer. Amazingly we didn't find one mouse nest or any signs of any mice in the whole car

There must be an efficient cat nearby.

Lol, No cat, I asked if he had mice issues. The previous owner said if you leave the widows down mice won't go into the cars. I find that hard to believe though.

Here's another angle

This is pretty cool or I think it is. These are the original license plates for the car stamped 63. They came with the car when Clark bought it in 1988. The last registration decal is 88 and it was just scotch tape on over the the 1974 sticker. Also this car has not been registered since then either. Clark the 3 owner whom we purchased it from never registered or titled it in his name.

Wow,just keeps getting better! Great car and great story!

So Clark never drove the car,it just sat in his garage?!
