it is a ph1 172, with nothing in it at all, plastic windows, basic wiring loom, door and boot skins cut out, alloy bonnet, one seat, no dash just the wheel, our clio is much lighter than 980kg, i would guess it to be about 750kg, and frontera is 1727kg (2.2 tdi) add all these together = 3177kg.
The weights are all based on unladed units also, so tools, and wheels etc are not going to be included, even if they where, they will not total over 300kg considering they are only 15" and we only take one 20l tin each time!
