Yes, from what I've read and experienced, the Prelude is the only sports coupe that Honda makes...

It has the classic features of a sports car, that neither a Civic or a Del sol has...
-Long, sloping hood
-low roofline
-low sitting height
-sporty tires-Stock (small sidewall for better handling)

Now, the S2000 is close, but it is technically a roadster....
As for the Del sol and the CRX, come on man, these are economy cars, peiod.
Maybe the Del Sol VTEC is sporty, but it is still an economy car...
