I wouldnt rush into anything if you have 10k cash to play around with.
my first mustang was a white 01 gt. It had 76k miles and all the modifications you could think of. all the bolt ons 3.73 gears, it was cammed and a ******* beast overall i only payed 4100 for it.
now i have a 2000 mustang gt with 75k miles 3.73, flowmaster exhaust K&N intake and it runs and looks great. the leather is flawless along with the paint and payed 4800 bucks
you gotta look around, wait, amnd find an oppurtunity to negotiate because i talked both guys down from 8k
