+1 .....no one is gonna want to spend 7 or 8 grand on a V6 mustang with 90k on it when you can buy a GT for that. Mods decrease the value. Best bet would be take off as many mods as you can and sell them individually.KBB are bogus numbers use NADA it is what banks use and they wont give you more for a loan than trade-in, most people buying a car from a private seller will need to get a loan from a bank so NADA is your best number to go off
I sold my mustang back in july, 2000 v6, 96k miles, custom electric green paint, saleen body kit, bluetooth headunit, JL speakers, CAI, full custom dual exhaust with flows 40s and and crossover bar, shiftkit, and tune.
We sold it for 6k and had a hard time getting that out of it honestly dont expect over 6.5 and a dealer will give you about 3.5k for it
