I wouldn't sell my 90 for any less then £7500 and its a 1985 200tdi, but it has lots of extras
I agree serten mods are work the money but only to the right person, I have no idea on how to value something like yours or mine,
Mine just got 12 months mot 2 days ago, caged spots on cage, rear locker front trutrac, 2" lift with +2" dampers poly bushed,5x insa turbo special tracks o. Wellers, NATO hitch front extreme winch bumper, warn xd9000 winch resent strip down and clean, new solinoid wonder lead and dash switch, synthetic rope, diff guards steering guard, rock sliders, cb radio, alpine stereo, electric fan extended breather to top of snorkel wading plugs.
recent work
New bearings all round, new front discs and pads, rear pads rear calipers. All fluids changed, new thermostat new front half shaft and cv, probs loads more i carnt rember,
It's only worth what some one is willing to pay,
I think 3k for a 300tdi that's solid is fair, as for what all the mods total I don't want to add it up never mind all my time,
