Sold my old 05 Tahoe last year and now I'm one of the people that is looking for a used truck in this crazy market. Currently looking at a base model 2015 Silverado work truck with over 270k km (which is almost 200k miles for my American friends here . Mostly worried about the 4.3 v6 engine it has, as I read that it is not the same old 4.3 they've been using since forever. It introduces in 2014 and has AFM and direct injection. How is the reliability of these engines at higher km, especially in a place that sees extremely cold winter? I just want a simple and reliable truck that would last me a long time.
