I had one about 6 months back.
I was watching myself work on some secret project I was doing to my wifes Olds 98 out in the garage but I wasn't allowed intot he garage to see what it was. I wouldn't even let/tell myself what it was. Wierd huh.
Well after the me working on the car for weeks it was finally finished and I got to go for a drive in it. "Wow" I said "I swapped in an L67!!" "Yep, thats one of the upgrades" I replied. Just then my sons ricer friend pulled up next to me on the passenger side and said "Hey, whats with the fake exhaust?"
"Huh?" I said.
"You got dual set of dual tips but exhaust is only coming out of one tip on each side" he explained and then myself in the drivers seat reached down and flipped a switch. I could tell "something" just happened but not clear WHAT. "Go check now" the me driving demanded. And he did. He came back with a
look. "What did you do?" he asked
"Its kinda like On Demand 4 wheel drive" I saw myself reply and just then the light changed green and I floored it, spinning all 4 tires easily, leaving my sons ricer friend waaayyy behind.
" I put an L67 in the trunk too?" I asked
"why not? Theres even still plenty of room left! "
And two days later someone posted they did just about the same thing in a buick (i think) in P&B.
Ok, its not Bonneville but it was the closest I have.
