Hi lads and lassies, Just wanted to say hello to you all as a new member... I'm looking for information on buying a used diesel Legacy tourer. 2008 RE /REn with up to 80K miles and a full history. Is there anything to particularly watch out for? Thanks to anyone who can help and apologies if this is posted in the wrong place. I'll get the hang of it soon enough ...! Cheers, Rob
