The car is very nice and in great shape and the 4.1 LSD has to make it a quick e30.
The Antenna doesn't work - points off
Torn Seat - points off
Craked Dash - points off
Its a nice e30 but its not worth $5100, for that much you should be able to find one without the faults listed above (torn seats and cracked dashes will be a common sight in a lot of e30s.)
