The cars I have are from RS and are the best deal ever! The have the softest tires I have ever seen. They have enough grip to hold on extremely well even on dusty surfaces (like a dirty hardwood floor for example) so the dirt isn't a prob. The cars are even sealed well. When I took it apart there is three screws to hold on the body. The motor pod has 4 screws to hold the top on. The motor endbell partially sticks out of the end too. It could use a rubber gasket around the motor to seal anything out but otherwise good. It also has a lexan shield that will cover it from dirt from the top but not the bottom. I am sure there is ways of shielding the bottom. The body top has a gold or copper plated antenna glued in. It has a wire running down to the PCB. The actual antenna looks like this:

It performs well but...
It will probably help to do the relay mod due to being fairly slow but otherwise very good cars! I would reccomend one very much! Especially for $15 at RS.
