I am 66 years young (yeah right) have driven 14 cars in my lifetime. All German, Swedish and semi English brands, even two frog cars......Last one was a Toyota Land Cruiser. Worse among them were no surprise Land Rover. What a overpriced piece of SHITE. Best and most reliable was the Toyota...
HI-YO SILVER gets lots of loving. Wash every week. Plus here in the tropics we have at the moment Monsoon rains from Hell.
