Hey I do know there is no gas so no fuel pump and delivery system. I do know there is no radiator so therefore no thermostat, antifreeze or sending unit, hoses, or worries about blowing a head gasket and having coolant burn off. I do know there is no oil so therefore no oil pump, filter , and frequent changes. I do know there is know engine management system with a barrage of sensors to keep fuel management in line. .... No knock sensors, no crank sensors, no O2 sensors and I do know there are no plugs, coils, fuel rails, injectors, turbos's, gas tanks, oil pans, rad fans or anything like that to consider either. 

Electronics .... sure but then what modern car doesn't have them. I don't know which of you two seem more out of touch with reality. But I'm sure the ecology nerds have no clue eh .... lol.
