My question is what do you plan to do with the cars. If you are flipping them, and have an equal amount invested in each car, I would say the Challenger. If you plan to keep one, I would say Cuda. This depends on what you already have into each car. For instance, if you got the Cuda dirt cheap, then the extra $20,000 would not be so bad of an investment. Especially, if you already have $20,000 into the Challenger. There are many aspects to the equation.
