Thanks for all the replies...

I still couldn't find anything in my area that will allow me to earn miles on any programs...

One dealer agreed to let me pay for entire cost of a car with my Delta Skymiles card. However, they'll charge me $380 extra. The car itself is about $42000. That doesn't sound bad, an extra one percent in cost. I get 42000 Delta miles for $380. Still trying to see if other dealers will let me do this.
