I have an HPI RS4/RTR.
I'd love to get a more serious car, but this does just fine for parking lot bashing. Considering the only on-road track got bulldozed, there isn't anywhere we can take them anymore.
It has a .16 motor in it, but I've been thinking of upgrading and getting the optional 2 speed tranny.
I'd love to have a Serpent though, just can't justify the price for bashing it up and down the street.
