I wanted the Impulse RS SoOOooOo bad when that car came out.
It was essentially the Geo Storm (which Isuzu built) with AWD and the very same 160HP Turbo intercooled engine form the Lotus Elan.
I have seen a few of them turning up recently but most of them are pretty claped out by now.
I liked the round quad headlight front end much better than the Geo Storm (which consequently i wouldnt have been caught dead in)
One inherent handling flaw that the car has if similar to the GTI's. Under hard cornering it lifts a rear wheel and since there is no limited slip, the unweighted wheel just spins like a heathen with his hair on fire, slowing the car down...
Still among "the cars I'd like to own someday"
