I would go for the viper for sure.. just for the looks and the features.. looks good when your driving on the road
Dodge Viper, well if its the one in the pic anyway.. Ive seen some Vipers in real life that dont look as good as that.
Hmm, so your budget lets you decide - a $80,000 car or a £149,000 car? Seems like you've either got majorly confused, or you live life in a money-free world
If your going to buy, go for the Viper. It would cost you lot cheaper and it's a great car. Rent, go for the CL65. CL65 is an amazing car. I only wish I had a budget for either one of these .
The Viper is pure power and a hell of a looker. If you plan to do any trips where you will be behind the wheel for more then an hour or you are over about 6 foot 1 though the Viper will be uncomfortable. As for the Mercedes I don't know anything about the car. Personally I'd take the Viper.
