Financially, it does. If you can afford one you can afford the other.
We Cross-Shopped by price. I thought about an M3, 5 series, Mustang GT500, Future Camaro ZL1, 1M, Cayman S, C63, E Class. We even looked at cars from different price ranges such as the Carrera S to a Camaro SS. I know they don't make sense as far as what class they are in but they are all close in price and we ended up going with what was best for us. I think its funny when people say "You can't compare those cars, they are not the same" when in reality people will cross-shop what ever the hell they want! HAHA!
