Why 2000? arnt they identical to 98/99? If you do want it for low kms, I'd be making sure it has log books/ service history etc...
guessing those 70,xxx are from when the dash was changed.. lol
The only reason to tell is its condition really, how the motor runs, rust, rips/tears in drivers seat etc.
If I was you I'd stick to one that's been unmolested, that way you may have a bit more of
an idea on its actual odometer reading.
When I was looking for my 34 I spent nearly 12 months waiting for the "perfect" one to pop up, they are few and far between!
