Doc,
Stuart is correct about the Lotus cars. Of the "vintage" (which means up to 1931 in the UK but something else in the US) cars, I think the first one is some sort of pastiche, the 1970s Wolfrace wheels being something of a giveaway. The second one looks to be a Mercedes and the last one is a Bentley modified for racing.
How long ago did you take these? Perhaps mid 1980s? Post some more if you have them.
