Hi Easy Rider,
in fact all of these cars are in a different price bracket!
I haven't seen the CGT's interior in detail, so I couldn't discover the build quality. It does seem to be pretty massive and solid though - kudos to build a hyper-sportscar with such a fabulous interior!
The Zonda's interior is definately well done but it is a bit over the top design-wise. I would want to change a few bits and pieces - the overall impression and performane of this car is undeniable superb though.
Haven't seen the F430's interior in person, so can't judge on that one. Based on the pictures and previous Ferraris I'd say its on one level with Porsche's 996?
The Bentley Continental has a nice and plush interior, but it didn't really speak to me. Might be that I have been unfocused while talking but it did not really strike me. Something was lacking...
I am still fond of the 993's interior. It might be ancient looking but had an outstanding build quality. I remember a relative's fully loaded C4 cab with wooden dash panels (something I would mind) which had been fabricated on a top-notch level. I'd say Bentley wouldn't do this any better...
