I got a 1992 110 CSW and the doors were also knackered. That was the liest of my problems... I quite enjoy working on my landy, but to get it through the MOT it needed sever things.
Rear crossmember - took ages, if you do it, pay the extra couple of quid for the one with the fittings (cost £120 inc rods and discs)
Refurbished the steering box (took even longer paid a garage to use their hydrolic(sp?) press, cost about £40)
changed the shocks cos they were leaking (quite easy cost £90 cos I got yellow ones!!)
the other jobs I've done are cosmetic, but now there are two major jobs,
The main thrust bearing is going and I'm not about to do it myself (£160 ish)
The steering pump is airating the fluid, (I'm refurbing the pump, cost £10 ish )
I think if you were to pay a garage to do these jobs it would cost a pretty penny. If I was going to take the ca to a garage, I'd get the best one I could afford, if, like me, you enjoy repairing things your self, its not so critical to get a pristene example.
