Extended warranty coverage.
Cars and trucks are built to last longer than in the past, so they'd need longer warranties, right? Actually, the basic warranties themselves are longer than past ones, so the need to buy an extended warranty isn't necessarily-well, warranted. If you feel that you absolutely require extra coverage, then buy it from an independent source when you need it. You'll definitely get a better deal than from the dealership.
Window etching.
This involves etching the Vehicle Identification Number (VIN) onto you car's or truck's window. The dealership will claim that this will help to trace your car if it's stolen. First of all, that likely won't prevent thieves from stealing your car or truck. Also, you could purchase an inexpensive kit and then do the etching yourself!
Rust-proofing.
While this sounds like something to make your car or truck better, there's more to it than that. This option can cost big bucks, and basically is a redundant feature. The warranties for today's vehicles tend to cover rust protection that lasts for many years. Be particularly wary if a car or truck dealer tells you that they've already added the rust-proofing. An "option" is just that!

Paint Sealant.
The product that the dealership uses is often the same as one that you can find in your friendly neighborhood auto parts store. So instead of having the dealerships do it, it would be more logical to do it yourself.
Car Alarm.
Having a car alarm installed on your car can certainly help to lower your auto insurance rates. Also, it's indeed more convenient for an auto dealership to install the alarm, than for an outside company to do it. That said, there are a few drawbacks to that option. You could end up paying too much for a low-quality alarm.
CD Changer.
It's highly advisable to have a CD changer in your car or truck, to avoid the hassle (and danger) of manually changing CDs while on the middle of a highway. The problem with getting your CD changer from the dealership is that is that you could pay too much for an inferior quality unit. Besides that, you might determine that newer technology might suit your needs better than a CD changer does.
Fabric protection.
Fabric protection provides you with fabric protection that safeguards it from stains. This miracle substance is Scotchgard, which you could purchase and install yourself. And to top it all off, you could save yourself a few hundred dollars in the process.
