In 2000 I purchased a 95 Viper that I did a lot of track events with and open road racing. Most fun car I have ever owned. Lost it in a messy divorce in 2013. I now have a 2015 Corvette that I have had for 2 years and a 2009 Viper that I have owned for a year. Vette's in CA. it seems they are like toilets. Everybody has one, but the technology far outclasses the Viper. Besides the Heads up Display I really like the Passive keyless entry and push button start and stop. There are a lot of aftermarket kits on the market, and I have been researching quite a few and so far, the only ones I have found say they are not compatible with a vehicle that has a push button start system. Can anyone explain why this is? has anyone here installed this system in their car. I intend to try and see how it works.
