This severely limits your ability to claim write-offs for the new car.

If, for example, you are disposing of a large SUV or truck, you may have a taxable gain since you may have already reduced the basis of the car substantially (remember that vehicles that weigh more than 6,000 pounds are not subject to the depreciation dollar limits).
