From personal experience, don't be swayed by the temptation of mileage. We had a verbal agreement on the phone for a specific # of miles from Fisher Honda in Boulder, for the purchase of a specific car at this dealership. When all was said and done the dealer renigged on his agreement for mileage. We walked and by the way bought the same car with a $250 upgrade for the same negotiated price at another dealer, the same night. Amazing the first dealer would lose a sale over 3500 miles when obviously with the second dealer there was room in the price to throw in the upgrade. I think the dealer miles program may be a bit like the idine program where some of the participants are scraping for customers for a reason.
