2003 Radical SR3 Chassie number 111 (Green Tiger), I have always wanted a Radical since I first saw one in 2002, I bought this car in 2017 and loved it just like all the other owners. I really don’t want to sell it but work and cancer seem to always get in the way. Extensive updates and modifications over the years. This Radical spent most of its life on the west coast and raced in the SCCA Runoffs in 2009 and 2010. It has spent the last 10 years as a track day car. Since I have owned it I made a point for this car to be easy to use and not a hassle to take to the track. Racing needs to be fun and that was my goal with building this car.  The newly added GARMIN Catalyst video system is really slick. Car has all fresh fluids and just had a new alignment and corner balance done.
