I'm going to date myself here and do a link to the outside, but I think it's worth it.
When I was 15 years old, that would be 41 years ago, I helped my neighbor's dad work on his cars. I did all things, from detailing the cars to helping him rebuild engines, but mostly I washed, waxed and polished - under close supervision!
He raced these cars you see, and had a number of them but two of them lived in the garages, most always in pristine condition thanks to my elbow grease. It had it's rewards. I got to drive them

. Granted, at the time these cars were not incredibly expensive but I can only imagine what they are worth now. I cant' even find a record for one of them.
The first was a 1957 or so Ferrari 250 GT California Spyder. It looked very, very close to this one:
250 GT
Same color and all, except that the tires were taller, skinnier the brakes were huge drums, and the interior was black leather. It ran on a V12 with twin distributors. The prettiest sounding engine in the world. I got to drive it. The clutch was so sprung that my leg would shake when stopped with the clutch pedal down. It was a four speed, and one time I did 120mph in third. Don't know where the car is now...
The other car was my favorite - A 1958 Porsche Carrera Speedster "GS" Cabriolet. I think GS because it had a twin cam, twin distributor, twin spark plugs per cylinder engine running on twin dual barrel Weber Carbs. I know because I helped rebuild the engine. It was silver with gold emblems and burgundy leather. Very fast and it turned like on rails. I can't even find a picture of one on the internet so God only knows how many are left and what they go for.
So, maybe not then, but how expensive would they be now

.
Best,
Jose
