2011 BMW 5 Series Sedan 535i 4dr Sedan (3.0L 6cyl Turbo 6M)
Owned for 6 years
 Have had the 535 Sport package for 6 years/70,000 miles so far.  Still like new with not a squeak or a rattle - a traditional solid built tank.  All materials still like new and no problems.  Previously replaced cars every 3 or 4 years, but now I find little logic in doing so since it is still like a new car, and maintenance has basically been just oil changes and brakes have been lasting a long time.  Can't believe the blue book value for the car is incredibly low now.  I have a deposit for a Tesla Model 3, but I can probably hold onto this car for another 10 years and be better off, so may not get the Tesla.  I'm still not bored of it, and still all original, except for replacing the run-flat tires with regular Continental tires that have provided a surreal quality experience.
