I have a friend that had recently purchased a 3000GT VR4 a decade or so ago. He was kind of the dork of our group - very much a part of our crew, but the guy we always picked on. He also came from a ton of money and was very hard on cars, so almost monthly he was getting something new (to him) and they were usually of this variety (RX-7, a couple Porsches, a Ferrari 308 and several Corvettes).
Anyway, he's had the car for two days or so and I have a good friend come into town. We were at a party at another friend's farm house and my buddy has brought his new toy. I ask my buddy who owns the car, if I can take my friend from out of town on a ride around the block in it. He tells me yes and we leave out - and me (being ~20ish and in a car like that) proceed to pull over every couple hundred feet and dump the clutch. Those cars all have AWD, but also have a good amount of horsepower. I was kind of disappointed that it wasn't burning a wheel as well as I'd hoped, so as soon as it'd catch, I'd stop, rev it up and try it again. I've got many years experience racing everything from dirt bikes to go-karts to dragsters (and even some planes - why I'm in this thread) - so I definitely know how to push a car to it's limits. But honestly, I came away a little disappointed in that whole test drive, as far as burning a wheel goes.
Anyway, I get back to the party to find the entire crowd outside. My friend that owned the car is standing outside and he is pissed off. He's screaming and everyone there is telling me that they could hear every bit of what I was doing. (Turns out that even though I drove a couple miles away, as the crow flies, I was only a couple hundred yards from this party house. They heard it all.)
My friend is also fairly intoxicated and is screaming - "What if I did that to your car?!?" On that particular day, I was driving an old jeep that I used for rock crawling - it couldn't get out of it's own way. So, I tell him go ahead and do his best. He walks off, then comes back with a rock and throws it at the side of my jeep. Again, that thing had been flopped on it's side and buried in mud - that rock didn't hurt the jeep, nor my feelings. I tell him "ok" and am honestly thinking that I'd be pissed if I were him too - if throwing a rock at my car makes him feel any better, fine with me.
I guess my absence of anger made him believe that I was extremely upset or something. He starts apologizing for throwing the rock at my car and making a scene in front of the whole party. I'm telling him it's no big deal and e walks over, grabs a bigger rock and throws it into the side of that 3000GT. Needless to say, that rock hurt his car much worse than mine, and an "ahhhhh" fell over the whole crowd watching this nonsense.
He then spent the whole rest of the night apologizing for "hurting my jeep" while we all stared at this huge dent in his driver's door.
The next day he calls me and says he needs some help - he tells me where he's at, and turns out it's right down the street from my house. I show up and he's standing on the side of the road, right beside his VR4 - which is upside down in a ditch. So, in the grand scheme of things, that rock didn't do much either.
Anyway - that's my story of when I peeled out in my friend's new-used car without permission.
