I started out with RTR some years ago; but, "graduated" from it to kits within 3 months.
If you are already in r/c racing and have some experience, I would suggest buying a new kit. So, you can build and tailor it to YOUR needs. Building is half the fun for many of us.
Another option is to buy a complete used car locally.
Great that you are keeping it fun!
