I voted "two" for number of diesel "vehicles" in the family but I didn't count our 18 hp Kubota diesel lawn tractor!
If you include the Kubota, we have THREE diesels, and two gassers. One of the gassers is my Beechraft, currently sitting in the hangar undergoing some preventive maintenance this winter. I'd love to get one of the new aircraft diesel engines for it, but at $35k, it would be worth nearly as much as the plane itself, and would put back my retirement to, oh, maybe age 105...
The other is our Honda Odyssey van, which was sitting ice encrusted for three weeks in our back yard. I finally chipped away at the ice and drove it 'round the block to keep it alive. I may drive it to church tomorrow (35 km) for the same reason. We hardly ever drive it now.
Mrs. PlaneCrazy MD drives the Jetta wagon, and I drive the Passat.
