92 mazda Mx-3 runs like a champ.
Well needs some cosmetic work…. 
But car is solid and still looks good.
And is pre electronic ignition.

In the background is the 2003 Camry a close runner up

BUT TO TAKE THE CAKE:
I once and a 1976 240 diesel Benz 450,000 miles and the car only needed an engine overhaul. With a Mechanical fuel pump and no electronics needed I once drove from Los Alamos NM to St. Louis MO with no battery and no working alternator, confidently across a desert.

Another great one is any pre 2008 ML 350 is the best engine ever made.  Just a solid car and 4-matic.
