I agree with what twobjshelbys said.

Also, one of the best ways to see to see the differences in person is to contact your local Cobra club and attend one of their meetings. Most clubs have enough variety in makes and models that you can see the similarities and differences in person.

I think there is a Long Island club and maybe some others near you. Look in the "Club Forums" section here to see who is near to you.

Good luck!
