How much to pay for an old Yamaha DT 50?

[ninja_butler]

I was thinking of buying an DT 50 as a quick & simple fix-up project but after a bit of research there seems to be a lot of them selling for well under £300 with tax & MOT so I'm now wondering if the one I was looking at is worth it after all.

I'm surprised how cheap they are, I saw an ad for a 2004 DT 50 in need of an exhaust for £400.

This one looks basically tidy, just tatty paintwork and plastics, but what's it worth without T&T?

edit* btw, it sold for £395.
