I'm after a cheap Ml diesel....anyone have one kicking about

[silverback mike]

Bit of an offbeat question I know however the cars I've bought from fellow phers are a decent bet. So I'm after a 4x4 with a towbar to lug my son and his karting stuff and a large german shepherd around. I have a budget of 2k as it's a work tool. I especially like the feel of an ml but would have to be a diesel.
If there's one out there in ph land give me a shout
