Sadly, all good things must come to an end. This applies to that final season of "Breaking Bad" you've been watching as well as relationship with your car.

But what do you do once you've decided that it's time for you and your beloved car to part ways? Selling your car can be a complicated and intimidating process, especially if it's your first time. Fortunately, with the right knowledge and preparation, it doesn't have to be.

Whether you opt for a trade-in at the dealer or want to take the leap and sell your car yourself, there are a few steps in the process you shouldn't overlook. Keep these tips in mind.

Plan for first impressions
We all know that it's what's on the inside that really counts, but when it comes to selling cars, that isn't necessarily true. While it's obviously important to have your car in great working order if you're trying to sell it, don't neglect the more aesthetic aspects of your vehicle. Like it or not, potential buyers are going to make their first impression of your car based primarily on what it looks like, so a dirty paint job and drab interior upholstery aren't doing you any favors. When you decide to sell your car, your first step should be to wash it and clean the interior thoroughly, so you can show off your ride with pride to those who may be owning it next.

Get it inspected
Nobody likes being burned by purchasing a lemon, so take care not to put another person in that same situation. Have your car inspected by a trusted mechanic before you sell it so that any maintenance issues can be pointed out and fixed. If you forego this step, you're simply giving buyers more ammunition to drive your asking price down.

Do your homework
Do you know off the top of your head how much your car is worth? Chances are, probably not. It's crucial that you take time to look up estimated values of your car based on make, model, mileage and age. Sites such as Edmunds and Kelley Blue Book provide free online tools that can do this for you. Just be aware that these figures are guidelines only – the value of your individual car may be more or less depending on a variety of factors.

When you're ready to sell your car and move on to another one, head to NJ State Auto Auction. You can trade in your existing vehicle for one of hundreds of Carfax-certified cars, all with the help and guidance of friendly sales staff.
