Buying the right Series III

I have a 2007 Disco 3 Auto diesel which is a great vehicle but kind of does everything for itself. I'm thinking of buying also a Series III for short journeys and a bit of off-road use. I'd prefer a diesel but am told the 2.25 litre standard unit isn't the greatest and can have starting problems. I've been offered a fairly unmolested 1972 Series III hardtop but with a later 2.5 litre LR non-turbo diesel fitted. It has overdrive but no free wheeling hubs. Vehicle has done under 80,000 miles (not sure how many the 2.5 engine has done). I'd appreciate some advice as to whether this should be a good combination and what sort of mpg I could expect from general road use. Also can anyone direct me to an idiots guide as to what to check out in a Series III prior to purchase (body, chassis and mechanical) e.g what areas of the chassis and bulkhead to inspect for rot. I'm fairly mechanically minded and am not afraid to crawl underneath with a torch, small hammer and large tyre lever!
Thanks in anticipation

Check all parts of the chassis and the bulkhead for rust. Outriggers are available as is rear crossmember, rear 1/4 chassis and 1/2 chassis. Front dumb irons are available also. Bulkhead footwell panels and door hinge and outer upper bulkhead panels are also available. Corrosion on the tub contact points with the chassis brackets can be a problem. Check the springs for sag and condition of the bushes.There will probably be a bit play in the steering but shouldnt be too much. All these are fixable but will affect purchase price. Good luck and post some photos when you buy one.

And don't believe everything you hear

Thanks for the feedback. I've finally bought a 1983 SWB Series 3 Station Wagon with heavy duty galvanised chassis, overhauled petrol engine, recent new springs and shock absorbers, plus new clutch, radiator and petrol tank. It seems to go well but have ordered a few new bits, mainly cosmetic, to improve its looks. It had done only 66,600 miles from new and its last owner had it for about 28 years.

The sounds like a good buy. Any photos? I think you'll find the petrol engine better than a diesel. They are easy to maintain and reliable if serviced regularly.Freewheeling hubs are a good option.

The 2.25 is bomb proof.

Miles better than the clatter box diesel

I recently chose the petrol over the diesel and its great. Strong, reliable and easy to fix/gain access. I was put off the diesel as 'apparently' there a bugger to start in the cold.
