I am in the process of building a Metro as a pizza delivery vehicle. Sadly though, the one I have is an automatic. Thus, I was shopping around for a 5 speed parts car. Lo and behold, I found a 3 cylinder 5 speed 4 door today for $250. It both runs and drives and is not in bad overall condition. It has an oil leak, something wasted in the front suspension, and a few other minor issues but is rust free and drives fine. Supposedly the A/C works but the owner took the belt off because it wouldn't run right when it kicked on ( A/C is important when delivering in the summer in Florida). I plan to fix it's issues and get it on the road in the next couple of days. Hopefully, 40+ city mpg is no longer a distant dream and I can now start saving money by the end of the week.
