Sure, I would prefer the 4.0, but my 2.5 tools down the highway just fine as long as you keep it under 65. No long Interstate trips recommended, but crawling around the farm in low range... not a problem at all. Local into town and back are perfect. The reason I bought it, high mileage and all, was because of a super price, no rust (I mean NONE) anywhere, very little oil leakage and everything works except the dash clock. Everything. I would say if you find a 2.5 that pushes all your buttons, get it. If you find a 4.0 that does the same thing, then get that.
