I just purchased a 1999 mustange GT for my wife and it has the 35th annv
emblems on the sides, I'm not sure if it is an annv. unit so I have added the vin. # in this post. #1FAFP45X5XF230133. If someone could help, thanks.

[Red9935thGT]

Easy way to tell is if the seats are two toned, does the car have black and silver colored seats?

According to your VIN# your Mustang is a standard GT, not the 1999 Limited Edition.
