Hello there. My family has owned Skoda's for the last 10 plus years when they were taken over by V.W. I drive a scout (2010) plate (previously my father's) covered 80k miles, no problems so far. Fantastic ride and has some lovely little luxury extras too. I get around 450 miles out of a tank. As for the Yeti my father purchased one last year as my mum had a hip replacement and wanted something a little higher up. He likes it, yet he wishes to buy another scout at the end of the year. The yeti drinks more than the Scout and the ride is a bit more uncomfortable, also the boot capacity is tiny to the scout especially if you want a spare wheel instead of the puncture repair kit, which seems to come with most modern cars now. As you said about log collecting. the scout is longer and can more weight. The 4 wheel drive on the scout has worked out well. It runs on an automatic system that when it feel the front wheels slipping the 4x4 kicks in, so the 4 wheel is not always running. For 5k you can pick some good ones up they will be high millage, but seeing as they now have a v.w engine inside them as long as maintained and serviced they will keep going. I hope this helps.
Kind Regards
Tom
