Found a photo of the floor just after I painted it. I can tell when it was because it is still clean and there is not piles of parts and tools all over the place.
My Challenger had to stand outside on the driveway for about 13 years? British garages in towns are built just large enough to take a small car with nothing else in it. Unless you have a lot of money of course. So I had to wait until I could afford to replace my original garage with something bigger. When I bought the house the main attraction was the extra 6-foot of land at the side that most houses in this area do not have.
The back third of the new garage is a kitchen extension and utility room. Well I had to sell the idea to my wife somehow didn't I?
