GM = bankrupt

One major reason GM went bankrupt is they managed to get themselves a reputation for shoddy products. Back when I last bought a new car (in 2000) I started off with a very eclectic list that had vehicles that didn't get a unreliable rating from Consumer Reports and cost less than $30K list price.  Gave me about 50 models to pare down via other info, but even at that early stage of my search, not a single GM car made that quite unselective list.  (To be fair, GM did have some reliable vehicles above my price point back then.)  Ford and Chrysler both managed to get a model or two on that list.  My 2000 Camry is still running fine today and I am unlikely to buy a replacement anytime soon.

Deadman, the best engine for normal passenger car use, as an engine and aside from other issues, is an inline six cylinder:

My old Dodge Dart had an inline six!  Dang thing as an absolute TANK!

An accidental tank, but still quite reliable.  Chrysler had originally intended to make the slant-6 engine for the Valiant/Dart out of aluminum to save weight but ran into engineering problems with mass production so they reverted to their fall back position of using cast iron, which gave them a heavier but tougher engine.  Had they managed to build it out of aluminum they'd hae gotten better performance at the cost of reduced reliability.
