I did my first serious test drive on 1/17/2008. I now drive it several times a week for various local activities. After beefing up the springs I settled on six batteries. I can now cruise at 45 mph and have a range of 15+ miles on my hilly local roads. My grandson Richard has been helping me on this and we still have instrumentation and beautification to complete.
