Hi all. I know this isn't strictly related to investing but I trust members opinions here. Any comments appreciated.

I've filed Sole Prop business taxes on a schedule C for 98, 99 and now 2000. I've always used the standard mileage rate deduction. I traded in my car in 2000 for a new one.

Turbotax now wants to know the cost basis of my old car when I put it in service (June of 98). When I click show form, it's filling out Form 8824. It looks like it's trying to figure out depreciation because of the sale (trade in). Is this necessary? I thought all depreciation was included in the standard mileage rate. Why should it matter that I traded in my car for a new one?

If this form does have to be completed, does anyone know where I can get historical fair market values for a car? Obviously, my biggest problem is I don't have that data. If I did, I'd just complete the form. I need to have cost basis of my old car as of June of 98.

Thanks in advance

Was the car new or used when you put in in service? If new, the value would be what you paid for it. If used, try a local bank or credit union to see if they have old editions of Kelley Blue Book. Also some libraries have these books. Worst case, go to www.kelleybluebook.com and look up the trade in value for the same model car that would be the same age today as yours was in 1998.
