I found myself wondering the same thing when I bought my Stinger.  “Why have I never seen an ad for this car?!”  But then I realized that there are lots of cars I’ve never seen a television ad for ... the Corvette, the Mustang, the Camaro, the Challenger Hell Cat, the WRX STi, any Alfa, Genesis, on and on.  It’s as if the manufacturers advertise for their bread and butter models, perhaps where the competition for market share is very stiff ... compacts, sub-compacts, mini vans and SUVs ... and leave the rest of their model line up to be discovered by visiting their showrooms or (more often these days) their websites to ‘build and price’.  I have only ever seen 1 Stinger prior to buying mine - in a drive thru line up ahead of me - but it caught my eye enough that I made sure I hunted it down to find out what it was as soon as I was in front of a computer.  “Build it and they will come” ???
