OK guys here is what I am looking at, please give input good or bad and anything else. thank you in advance.

02 Audi A6 3.0l quattro- US car with no rust, 190K (kms),
02 audi a4 3.0 quattro 200k Auto
02 vw w8 187k auto

I know nothing about these engines, good or bad and had never even heard of the w8 before tody. all cars look ti be in great exterior shape. Need to make up mind ASAP

 

I have heard that the W8 block is not the best engineering decision VW ever made. I found this out cruising several VW/Audi forums, years ago when I was fiending for a W8-Passat to mod on. Everybody, and I do mean EVERYbody warned me away from them. That being said, the problem they warned me against (something having to do with the crank and/or crank-walk IIRC... Maybe hit VWVortex.xom and troll their boards) more than likely would have presented itself long before 187kms, as it wasn't a "all cars of this model have that problem, and more of a "luck-of-the-draw" kinda thing that VW would fight, tooth-and-nail to NOT be culpable for. I think the solution was something simple like: punch-out the counter-weights on teh balance shaft, or, just "punch" them so the counter-weights don't "walk." It's been almost a decade since I cared. So, that's what I know about the W8.

As far as the pair of 3-litre's go, meh... Same engine, so, it boils down to what size car you want, teh trim-level of the respective cars. Or, both.
