I picked up a red viper with black stripes, it's my 1st American vehicle and I love it, I would like a little more power.I have a 2013 CLS 63 that I took to renntech and had the ecu remapped that gives me 669hp and 734 torque at the crank 0-60 3.4 on d.o.t. tires and 11.34 @ 125mph , very similar to my viper .The power comes on different so I can't say which one is faster all I know is the viper looks like it should be way faster of the two lol, so that's my mission to get as much hp as I can without nos or forced induction. I'm so in love with this car can't stop going into the garage and looking at it .I've known for a while the they're having a hard time moving vipers and are given massive discounts, so when I saw a 2014 slightly used srt with 1300 miles on it on sale for $85,000 I thought it was a great deal , I thought I got a even better deal when I got it for $83,000....but now I'm on the forums and seeing other great deals and it's ruining my brand new car feeling.I keep feeling like i could have gotten a better deal ,yeah I know it's nothing I can do about it now but I can't stop thinking about it..anyways I'm loving every thing about it except the net storage instead of the clam shell in the gts and you can see right into the trunk because it has no cover but.... so glad I picked this car over the other choices I had in mind.
