MB ML320 third row seat???

[Monza_dh]

With the economy the way it is we have decided to hold on to my wife's 2000 ML320 for a little longer. Its running great but with three klids its tight in the back.

I'm trying to locate a single third row seat but only find expensive aftermarket units or two seats on ebay with no belts etc.

Since I am only looking for one seat does anyone have one third row seat or know where to find one? I need a seat, brackets and belts and dont care about the color, leather or cloth and it csan be right or left side.

Thanks!
