Stirring up a hornets nest

I drive my car a lot so I get plenty of unwanted comments and suggestions almost daily. My favorite are the "purists" and the Barret Jackson fanboy types at gas stations filling up their minivan or Camry's.

"Back in high school"
"A buddy of mine used to..."
"You know what you should do..."

"Sorry Dude, I need to get back to driving this car I enjoy while you take your Astrovan to the pharmacy and fill your low T prescription."
