Mitsubishi Express HELP!

[cboullier]

I'm looking at buying a van so i can do some backpacking around Australia. An ad for a 1994 Mistubishi Express Van has recently come up. the body is in good condition with roofracks/towbar/bullbar ect. it is also duel fuel of lpg/ulp. my main concern is that it has done 350,000kms already. i am informed that they have never had a problem with it and that it has a decent service history. From your knowledge and experience do you think that this van will still have a while left in it? its a good price and has safety cert. and 6months rego. if it had done 100,000 less i would be jumping all over it, however i am just a bit worried about the mileage its done, especially as australia is good at racking up the kms on vehicles!

hope you can help
