My humble brag(*) responding to AOPA’s airplane/car naming coincidence article(*) refers to this pair of beasts.
Now you know.

The article:

What’s in a name?
Aircraft and cars share monikers

By Peter A. Bedell

Some awful names have been affixed to vehicles meant to roll or soar […]
There's simply not enough magazine space to poke fun at all the horrid names of cars and airplanes of the airline, military, and GA ranks. So we limited this article to shared names of certified general aviation airplanes and automobiles.
Aztec/Aztek

Even though Piper's Aztec is not the prettiest of airplanes, to discuss it in the same paragraph as the Pontiac Aztek is almost offensive. Introduced for the 2001 model year, the Pontiac Aztek is one of those automobiles that make you wince - like seeing Rocky Balboa's face after a bout. […] the model was dropped after 2005.

Piper's Aztec is a heavy hauling twin […] It excels at hauling big loads out of short fields of nearly any surface. […] The Aztec lacks the sex appeal and speed of Cessna's 310 or Beechcraft's Baron but earned a loyal following until its discontinuation after the 1981 model year. […]

My letter:

Your article describes car/airplane-naming coincidences. It turns out that I am an exemplar owner - perhaps the only one - of the Aztec/Aztek one, because I own one of each! Both vehicles have quirks, but have proved to be dependable, capable, fun machines.
