Find this 1991 Mazda Eunos Cosmo offered for $11,000 in Bonney Lake, WA via craigslist. Tip from JB1025. 
Plenty of people don't like Japanese cars, whether they're rampant nationalists from Louisiana with a slightly unhealthy interest in 1930s German politics, or they're a stuck up arts professor who swears by his Citroen, but no one could say that Japan isn't technologically adventurous.

Find this 1996 Eunos 800M for sale in Cairns, QLD, for $2,000 AUD ($1,530 USD at the time of writing) via gumtree.
