JASON Davidson’s One Tonner may not be pretty, but it has a great personality in the form of a 10-second LS donk.

When Jason pulled this $125 HQ – yes Doreen, it has a later-model front – out of a chook shed a few years ago, the first order of business was a serious pressure clean inside and out. “The interior was full of dead rats, birds and poo; it was rank,” says Jason, from Abermain in the NSW Hunter Valley.

It’s just so much fun the way it is though, and no one gives it a second look.”
