Wow! It could be a little 700! If that last one IS a BMW 700, that's a rare find in the States. I would try and get him to part with it!
BTW: Giovanni Michelotti was responsible for the design of the 700. Michelotti is well known throughout the automotive design industry, especially for his work with the Triumph Herald.
Don't know about that shadowy first one but, to the right of that, the second one appears to be a Jaguar Mk. II....though the hood bulge looks a little Rover-ish, the C-pillars say "Jag". The third is unmistakeably Triumph Harald.
