Sorry, I can't find something about my last numbers; I have not a lot of time in these days so I think I'd better quit.
As you prefer, thank you for playing!
In case you change your idea here are the clues:
65017:TOURING, 1957 sounds like the start of a Spanish sentence to welcome someone in your house, but it's Japanese!
75017:MODEL 6-40 5-PASSENGER TOURING, 1920, from the States, anagram of Demo Pint.
5017:T2A SALOON TURBINE, 1954, this is easy, from a series of British sperimental cars but you can't find this brand, it closed (but don't tell it to chinese people!)
