I learned to drive a clutch on a Vespa P200e side car rig in a cow pasture when I was 6. Dad sat behind me and basically kept us upright while I drove.

3 years is a better pay back then some of the hybrid cars running around. And if your a farmer whom tends to fill his personal vehicles with non-road taxed farm diesel ,only by accident and in emergencies ;), the pay back will be shorter.
