Luxury marques of normal car brands

Also Ford & Lincoln, GM & Cadillac

Lincoln, Cadillac, Lexus are decent cars and will give you more features than anything under the standard marque; I'd say they compete with Audi, Mercedes, Land Rover. They're a step below something like a Lamborghini or Bentley though.

My Buick Electra certainly did. A beautiful car I was proud of. Dad gave it to me in my early 20's.

"Real?". Those European brands don't age well. Korean and Japanese vehicles generally are unkillable.
