If you have your heart set on Nitro, Look for a RTR, heck if you are even looking at electric go RTR.
What is RTR you ask, RTR means Ready to run. It comes with almost everything you will need to go out of the box. You will need fuel, batteries and maybe a few other small things. I like the touring cars the HPI makes. thier site is HPIracing.com. The RS4 RTR 3evo is a sweet car. And if you dont like the body just get a differant one.
And you can get it for around $320.
