Add Jabba's fossil fuel burning large capacity engine Land Cruiser into the equation, driving him to the airport and back and you have a carbon footprint half the size of Qantas. Oh what ever happened to the Global Warming swindle thread....
Back onto topic though.... if you need to ask you can't afford to own an aircraft, but that being said, they (the RV) should be considered to be highly cost-effective in terms of pocket-rocket type aircraft. Half the speed of an L39 at a tenth of the price.
