I'm gay, and I can say for certain that NONE of those vehicles on that list interest me in the slightest, lol. Maybe if the Merc is an E63 AMG wagon, simply for the badass sleeper factor. The VW stereotype has some truth to it though. Any man who drives a Jetta is gay until proven otherwise.
My first vehicle was an FJ; then I had a Tundra (crewmax 5.7L 4x4 SR5 with the TRD off-road package), and now my 4Runner (Trail)

I plan on keeping my Runner until I can afford a Mercedes G63 AMG. The G65 doesn't sound as nice as the 63, in my humble opinion.
In my experiences, gay men also often drive Nissan Altimas & Versas, Chevy Cruzes, and Dodge/Chrysler POS'.
As a total car nut, I can only dream of meeting a compatible guy who drives a 4Runner lol.
I'm surprised that Subaru wagons didn't make the list, which resonates with lesbians haha.
