| LPG is a good idea on something like a Range Rover where there is room to mount tanks under the chassis. As Bob says above you would lose the boot completely. And the backfires are certainly not good news, I have seen Range Rovers with the air filter box completely disintegrated as a result of this... not good with a turbo and all that electrickery and sensors... I would go for the Dooper (in fact I've had mine since September and love it)! |
