V One SIII is a very strong car, however have a look at the V One SIII Cup Edition 2. Very nice car with some very good hop ups. Be quick as I know they are only a limited edition.
I've been running a V One SIII (with a lot of hop ups) for some time now and it has a big and easy setup window. As a stock car you still can't go much wrong.
As SJL said, a lot of parts are interchangeable with the RRR. If you look at the front and rear of the car you will see that they are practically RRR, so parts are readily available.
