Maybe a Honda del Sol VTEC (Probably known as a CRX VTi in your neck of the woods). 170 hp I believe (again over on that side of the pond). Might be available to you with the trans-top (power removeable targa roof) but if not it still has a manual targa removable top. The last year they were available was the 1997 model year so you should be able to find one for a good price.

Other then that I agree with a used S2000.
