Rule change a 2-door car with less than 108 inch wheel base can be used if it is not a sports car and has a 4-cylinder engine. I don't want this to get out of control with a bunch of Thunder cars coming out of the wood work to out run everyone so please call and ask before you just show up with a 4-cylinder, 2 door car.

For the right amount of money I have a Caddilac for sale. It is set up for 2 people and can hold more if another seat was installed. It has a custom built cage and has run evey enduro race in Corpus and has finished every one it started. We also ran in Pleasanton. call for more information. James - 361-533-2809.


It will need a radiator and probably a battery for the next enduro.


There is a picture posted below. Dont let the looks detour you. It is a bit rough but it will still run.


If it does not sell I will run it at the upcomming Enduro.
