Ok, I am stumped. I own a small business. I can claim the car as a business asset and decuct it. The GMC site says the car is eligible for a $25,000 deduction. So far, the only way I qualify for that is if the car is over 6,000 LBS. Website says the car is 4700+- LBS. Anyone dealt with this issue? Is there a special tax break or are they figuring the Acadia counts as over 6,000 LBS? If not using the minimum 6,000 LB limit then my deduction is only like $3,000.
