James, those are the unique parts. You'll need all the rest to assemble a car if you don't have them already. Tamiya has a great database of assembly manuals that can get you acquainted with what you'll need to build a basic car.

Your best bet is a used roller from eBay or local used ads where you live. A basic, complete used car should run about $100. With upgrades, brushless systems $150-$200.
If you're able to find a NIB kit, try not to pay too much. Anything over $150 and you're padding a collector's wallet.
