I don't have one but we sell them at the LHS that I work at. I think they are great cars for starting out with. HPI has good parts quailty and availability, so when you break a suspension arm, which I know you will, you'll be able to get a replacement quickly and painlessly
. If you get the kit you will have to also buy: 2 channel radio with 2 servos, fuel, glowstarter, tire glue and body paint. If you get the RTR you will have to buy: fuel, glowstarter, tire glue and paint, plus you dont have to build it if you dont want to
. Personally, I think that you should get the kit because its good to know how the car goes together and makes it easier to do regular maintenance on them.
