Your habit of trading vehicle might have made sense 15 or 20 years ago, but modern vehicles and modern lubricants are vastly improved and extend the life of vehicles greatly. I drove a 1986 1/2 Nissan 4x4 with a teeny 2.4 liter 4-banger for 19 years and over 170,000 miles and all it ever needed was regular maintenance and a clutch. More recently I drove a GMC Canyon with the oddball 3.5 liter inline 5 cylinder engine for 115,000 miles and it never needed repair - only standard/regular maintenance. I am sure others can chime in with similar stories. It's just my opinion - although it is based on solid experience - that whoever buys your Raptor will enjoy a highly reliable top flight vehicle for years to come.
