Hm...
Voigtländer VF-101 - something classically European-sporty and small, but actually Asian underneath - maybe a
Mazda Cosmo
Voigtländer Brillant V6 - classically German, nice to look at but not high performance -
Porsche 356, probably the more sturdy and less sporty coupe version
Agfa Silette LK - got to be a Volkswagen I think... not a Beetle though, maybe a
Karmann Ghia since it's a bit stylish, but still functional.
My Japanese rangefinders (Taron Promaster, Yashica M, Minolta Hi-Matic 11, Yashica Lynx 5000) would all be Datsuns of various sorts. The Hi-Matic is a bit more shiny and has better glass, so it could be a
240Z (a.k.a. S30, Fairlady Z). The others would be 1960's-70's sedans.
My Nettar, however, would be something old, elegant, with nice leather and fabric bits, not high-powered, and easy to operate - the
Mercedes Simplex is a good fit.
Both of my DSLRs are boring, modern Japanese sedans.
