Hi there. I am new here and I feel that I should put some input first before I can unload numerous problems of my BMW.
Dennis, I need a mileage of the car, to get an accurate BB value. Also there is no exact value on the car. But based on 120k assumption, a 1998 M3 2dr will be between 17’751 and 21’651. As far as taxes are concerned, get ready to pay taxes on the greater value of the Black Book. But generally tax is calculated on the average of those two numbers.
Hopefully this answer has provided some help.
