The ED spreadsheet has some potential.
But I'm confused by some of the values already in there, like the base ED invoice price. Is that suppose to reflect the actual price or just some sample numbers?
Likewise, the prices for the options seem to be off. Like Premium Package would be $2000 or $2640, depending on whether it's a 330i or a 325i.
Also, not all options are listed. Didn't see Comfort Access or the Rear Power Shade.
One thing which might be nice is to be able to enter a sales tax rate and have it calculate that within the monthly payment and the driveoff costs.
