When you’re buying a car, you’ll often face a list of extra add-ons that dealers will try to sell you. These options might sound useful or important, but a lot of them end up just increasing the price without giving you much value.
Knowing which add-ons aren’t worth the money can help you save hundreds or even thousands of dollars. Understanding what to skip keeps your car purchase focused on what really matters, so you don’t overpay for things you don’t need.
Rust Protection Packages

Rust protection packages usually come with a hefty price tag, but unless you plan on keeping your car for 10 years or more, they’re often not worth it. If you do want rust protection, you can save money by getting a thin protective spray like Krown or Cosmoline independently each year.
Most newer cars already have decent rustproofing from the factory. So, paying extra for dealership packages is usually just a way for them to boost profit. You’re better off skipping it or shopping around for a fair price elsewhere.
VIN Etching
VIN etching is when the dealership scratches your car’s identification number onto the windows. It’s meant to deter theft, but you can get this done much cheaper elsewhere.
Dealers often charge $200 or more for something that costs them about $10. You don’t have to buy it, and it’s not a required service.
If they say it’s already included or non-negotiable, push back. This add-on is mostly a way for dealers to increase their profit with little extra value.
Extended Service Plans
Extended service plans often sound like a good idea because they promise extra coverage after your manufacturer’s warranty ends. But they can cost a lot and may overlap with what your original warranty already covers.
You might not end up using the plan at all. Many repairs are covered by the warranty or can be handled by a trusted mechanic for less. It’s smart to weigh the cost against the likelihood you’ll actually need the extra service.
Tire and Wheel Warranties
Tire and wheel warranties sound like a good idea, but they’re often overpriced. You might pay a lot upfront for something that’s rarely used.
Most issues with tires come from regular wear or damage you can catch early with proper care. Plus, your regular car insurance or credit card might already cover some repairs.
Dealers push these warranties because they add to their profit, not necessarily because they save you money. It’s usually smarter to skip them and save that cash.
Paint Protection Coatings
Paint protection coatings are often sold to you as a way to keep your car looking brand new. They promise to shield your paint from things like UV rays, bird droppings, and minor scratches.
But these coatings can be expensive, sometimes costing over $1,000. Plus, many need to be reapplied regularly, which adds to the cost over time.
You can usually find cheaper alternatives to apply yourself that offer similar protection without the dealer price tag. Most of the time, these add-ons aren’t necessary for everyday driving.
