If he's truly running low 11's...he has some significant mods on it probably beyond nitrous.....and would probably be selling it for more than $5000 OBO. Most lightly modded V8 mustangs I've seen at the track don't run much faster than low 13's high 12's at best. Most stock run high 14's and low 15's.....just a shade quicker than a bone stock DOHC.
