Shocking little cars, put together like something I've repaired whilst drunk and drive horribly. You sit massively offset to the pedals.
The streetka isn't the worst thing in the world if she likes them, though I'm not sure how they fair with the rust issued the rest of the range has. Mx5 as already mentioned, mr2 if you can find a facelift for the money.
You could also cut the budget right down and get an older megane convertible for 1k or less. Avoid the 2 litre ide engine and they probably fit the bill. French though so you'd need to find a decent one. Dirt cheap though and cheap parts though put together in a very "french" way.
