I'm on the lookout for a Landrover Defender 90 or 110 [prefur a 90] diesel and would like some hints from those in the know what to lookout for when going to view a used one. I've been around motorbikes most of my life, had a good few cars as well so not scared of getting mucky crawling about underneath or under the lid and just need to know what goes wrong and how to spot a duff one. Any hints would be most welcome.
