Haha, funny this is brought up....
Awhile back I was driving my brother in laws 03 vette, and everyime another vette passed me, new or old, POS, or badass, they waved. Well, i'm not a corvette owner, so I had no idea, I figured it was a vette thing, turned out it was.
ON THE OTHER HAND, since I bought my 04 GT, I never get a wave, I either get a rev, or a fly by, or a downshift. The most recent event inspired me to upgrade to a catless x pipe when a mach 1 in opposing traffic downshifted and took off like a bat outta hell. I would seriously like to find this guy becuase I gotta say, he had one of the most badass sounding stangs I think i've ever heard. A couple days later there had to have been a stang meet in my area because just on the golden mile, I passed and was passed by a countless number of stangs and cobras, all badass sounding, so I decided that I was tired of my "quiet" bassani catback. Either way, if your in delaware county, pennsylvania and you see me cruising around in my sonic blue GT, gimme a rev or a tappa tap on the gas (not a holla) and I'll know where your from.
