DB9, the engine sounds awesome, especially in tunnels with the windows down.

 

my old corolla was fun once you took it off road

but honestly, I have test driven pretty much every 'fun' car under $70k, but none of them were as fun as my s2k. The one car that I think may be more fun that I have yet to test drive is the Elise

 

Boxster (any trim)

RX-8

 

fun to drive?...check out that car called the miata. that's what it's all about. it is FUN to drive! i had one for several years and although my s2000 is much faster, more comfortable, better looking and pretty much better in every way, i miss that car. i couldn't stand to get another one because of the wide selection of cars out there. i am not disappointed with my selection of the s2000 don't get me wrong. certainly if you don't care about the fact that the miata isn't the fastest car around, take it for a spin and have a blast!

 

A rental car. Any rental car.
