Hmm, thanks for the wavs, i can't find the idle recording i made at the time, i can't believe i didn't check under the bonnet, but then, i didn't know there was a chance it could be anything but a v8.
I did however find the video where we tried to get the dang thing to shift!! man, it cut the power at 4k if it wasn't getting resistance so the donuts were hard to pull off (we had a dusty road, no room before the ditch at the roadside)
Anyway, it definately sounds v8, but wish i'd checked to be sure now.
Anyway, yeah, need a place to rent a v8 mustang from in portland oregon. I'd settle for the v6 if i could get a manual box.
Don't think i wo'nt drive a v6, i own one right now, but i don't live the states, the land of the v8, so when i drive there, i want the real thing

Its not all engine, i do like the mustang, but if you're driving an auto, its real hard to control the car when driving fast.
