I was driving my friends viper a few months ago and at the stop light a 550 Maranello pulls up. WHen the Light changed we both took of like bullets. I shot ahead of him, and kept pulling ahead. At about 120mph he slowly passes me and continues moving forward gradually until he was marginally ahead of me. I then backed off because the highway was heading in a dense city area. At the next light I congratulated the old man driving the Ferrari. I dont think it's justified to spend $150,000 more for the Ferrari over the viper. By the way radar jammers don't work, They do not help you in the least bit. A radar detector will only save you half of the time. My advice would be not to start relying on a radar detector because it gives you a false sense of security and you will get burned for it one day.
