gman,
For the past 4 years we have provided a 2yr/24k mile maintenance package included with all new and used cars we sell. Its a bunch of oil changes, tire rotates/balances and a couple details. Costs about $200 per car sold (split between new/used and service) expensed when the customer comes in. The total expense each month is about $9,000 (charged to advertising). We have about a 95% usage!
The results: GM will show you 'owner loyalty' figures. Also, you can have service-reminder-companies do the analysis: our result runs about 95% during the warranty period and about 85% post warranty.
What's the economic value? We generate about $40 gross per advertising $ spent and I think that's pretty strong compared to the $4 gross per ad$ average.
How come you don't do this? First of all, once started you can never stop. Second, most sales departments will cringe at the $4500 charge ($9k split) every month for cars sold months ago. But remember this: Service sells cars.
Try it, you'll like the results

ps. We started accumulating the $200 per car sold when the car was sold. Obviously, we generated a ton of money early and our tax accountant took that as income. Therefore, we now charge the expense as it occurs. This is also the advertising 'holy graile': you don't spend the money until AFTER the customer comes in.
