My last new vehicle was a 2004 Ford F150 XLT SuperCab 4X4, purchased new and driven for 12 years. It received very good regular maintenance (oil changes, transmission service, alignment, tire rotation, etc) and despite its 170,000 miles I had no doubt that it would easily go another 10 or 12 years. Unfortunately, it had also been pounded out by hail twice and struck on the side by a car sliding across a snowy intersection.
Had my wife convinced that I was getting a new pickup truck. Had her pick me up and drive to the dealership, where I had arranged to have her new car rolled out for her approval.
Sold the Ford truck. Took my wife's old car as my daily ride. Two-and-a-half years later (about 3 months ago) I bought a new Nissan Titan 4X4 truck. Everything I want and more (390HP V8, 7-spd automatic, AC, cruise), but nothing excessive (rubber floor mats, utilitarian upholstery, nothing that can't be hosed down when necessary). Now has about 4400 miles, including a 2600 mile road trip, and I think it will carry me through my remaining years (assuming no more hail storms or traffic incidents). 19.2 MPG on the road trip, by the way.
Wife's 2015 Nissan Altima SE looks like a keeper, with 19,000 trouble free miles, and a recent road trip averaging 38.4 MPG.
When I was in high school (50 years ago) we thought nothing about pulling a car into the garage overnight for a top-end, or bottom-end, job and have it ready to go by morning. Now I don't know what I'm looking at under the hood! All I know for sure is that good regular maintenance will make just about any new car last as long as the owner can use it.
