Eunos = import, yep. Your friend might find her insurance is a bit higher for an import vs a UK model, so maybe check first? Obviously if she has such experience that it only costs £300 to insure a car like this then it's not so much of an issue!
You'll find that *generally* the imports have more in the way of equipment - air con, fancier (although early 90s so still pretty crap lol) audio systems, leather interior, lowered suspension, limited edition versions with different wheels/interior trim, etc. But the cars will generally have patchier service history. The mechanics are identical on them
