If a dealer has already applied rustproofing, paint sealant, or fabric protection, you will have to pay for these treatments, but they often are overpriced. When dealers have outside vendors come to the dealership to apply these treatments on cars, the total cost to the dealer is usually less than $50 per car. If a dealer tries to charge you more than that, you can regard the cost simply as an extra markup. It’s better to buy from a dealer that applies these treatments to cars only after a customer requests them.
With regard to rustproofing, there are special problems. Many manufacturers recommend against dealer-installed rustproofing. Most say such rustproofing is unnecessary, and some are concerned that it will block weepholes and actually contribute to rust. Burglar alarm systems, wheel locks, and other add-ons may be worthwhile, but find out what other dealers and independent shops will charge for these items, if you want them, before you go to the dealer where you plan to buy. You can use the other firms’ prices as a negotiating standard or you can simply buy the add-ons from the other firms.
