Where are the cars located? Do you have titles for any of them?

I don't think that those cars are 380sl. The black one look like a 450sl. It has the 3 speed transmission; which the 380 didn't as far as I know. Also Mercedes didn't make a 380 in 77, only made 80-86. The silver one looks like 450sl also. Where are you located??
