Well after a year with my A6 mag ride vette and having it in the shop about half the time I finally traded it in. This after spending thousands on aftermarket accessories, burning up 3 computers at $500 a piece (chevy picked up the tab), and dealing with the idiots that took apart the car more times than I want to think about. Warning to all who want to put in aftermarket stereos with amps, speakers, and nav: It was an absolute nightmare. Countless dead batteries and issues. So i test drove the BMW M5 and was extremely impressed. Then I went to the Chevy dealership to order an '07 and send it to Callaway when I spotted a yellow '07 Z06 that was supposed to have been in NY. After I test drive with the rocketship I fell in love with it and it's now in my garage! This time the only stereo is 7.0L with 505 HP.
