Have you found a down side to the TDI Jetta? I've got to get me one of these cars.FlakMan said:I have a 1800 watt 120 volt/20 amp inverter mounted in my VW Jetta TDI. . . . . . My Jetta has a great voltage controller and engine will speed up as current draw increases. Your engine must be on to power an inverter for a resonable period of time.
