I can't speak for JasperPearl, but there's more to maintenance than that. There's tire rotations every 5K. There are air and fuel filters. Also, it may not seem like much but there are a number of inspections during each maintenance interval. The dealership will charge you an arm and a leg for those. Although I don't think $1000 is a steal, I doubt JasperPearl got ripped off. It's probably cheaper than going ala carte on the maintenance. From the dealer's perspective they have you locked in for maintenances since you've already paid for it.

My dealer has something similar. They give you six free oil changes when you purchase the car. They then sell you a coupon book for more services for around $600. I haven't looked into it. The dealership is a 1/2 hour away and I may just go to the local service station and save the receipts in case I need to prove maintenance is performed.
