How to Maximize Your Trade-In ValueMario Tama - Getty ImagesA hot used-car market doesn't share its heat with all sellers equally. If you decide to trade in your used car for something on a dealer lot, you can do several things to maximize your trade-in value. The Internet is full of advice on the topic, some of it contradictory. We spoke to a couple of dealer representatives to find out what really matters and why. Their advice ...Thoroughly Clean the Car You're Trading In"Most people are shocked at the variance in used vehicle values based on cosmetic condition," says Charlie Watson, marketing director at Mark Williams Auto Group in Cincinnati, Ohio.Alayna Wilkening - Car and DriverAn olfactory cleaning counts as well, because odors can be a huge issue. "Smoking kills the value of a car. Literally kills it," says Thad Marck, a sales consultant at Mercedes-Benz of Cincinnati. "You just can't sell a smoked-in car except to another smoker, and there just aren't that many of them."But even the lingering scent of stale food, like leftovers that have a habit of living in the back seat on hot summer days, can dent the value of a trade-in.Fix Any Maintenance Issues on Your Trade-InAddress any known issues afflicting your car—as well as any outstanding recalls—before getting an appraisal. If you've slacked off on regular maintenance, have a reputable shop go over the car.Unlike in a private party transaction, receipts won't do that much to help your case. "Chances are a manager will never read them, and we have to shred them right away," says Watson.Car and DriverThis is because receipts contain personal information the dealership cannot hold onto and can't show to a future customer. Vehicle-history sites keep track of maintenance done at many repair shops, which means the dealer will need to rely on that when dealing with buyers interested in your old car.Some sites advise against replacing tires, but that depends on the state of the rubber on the vehicle. If you have four matching tires with some evenly worn tread left, then you're not at risk of losing big money at trade-in.However, if you have a mismatched quartet of rubber and one tire shows severe cupping, then you'll want to replace the tires and fix the suspension issue causing the cupping. These issues will not just be noticed by an appraiser; they'll also raise other questions that can impact your car's trade-in value.Deal with minor fixes, such as paint blemishes and windshield cracks. However, don't worry about replacing scuffed or dirty floor mats. "We replace the floor mats anyway," says Marck.Be honest, as well. "Truthfulness makes an impact," says Marck. "If it's been wrecked and they don't tell you, it just makes for a difficult process, and you lose trust in what the car's going to be."If you're not trading in just yet but plan to, go easy on the car. "Be mindful of unnecessary wear from things like slamming your door," says Watson. "As petty as that may seem, it can cause internal components to break or rattle."Know Your Car's Value Before Getting an AppraisalCheck the value of your vehicle using various tools across the web, including our own. "Don't take [the result] as fact, but it's a good point of reference," says Watson.Car and DriverMarck adds that his dealership doesn't sell Hondas, but if someone wants to trade one in, the dealership uploads photos of the Honda to a virtual auction service called Appraisal Lane, where Honda dealers can bid on it. "And they're paying cash for the car," he says, "so that's what it's worth at the wholesale level."Carvana and CarMax will make guaranteed online offers, and CarMax will give your car a more thorough appraisal if you go to a brick-and-mortar location.With so much volatility in the market right now, the most up-to-date values will come from car sales like Car and Driver's own used-car marketplace. Look up your vehicle and trim to find out what dealers will try to sell a similar car for. This will provide the best idea of what you can expect for trade-in value, minus costs like reconditioning and, naturally, profit. Assuming you don't owe more on the vehicle than it's worth, such knowledge will also keep you from being lowballed.Negotiate Your Car's Trade-in Value SeparatelyCome to an agreement on the value of your trade-in and keep that separate from your new-to-you car negotiations. Don't let the salesperson combine the trade-in and the new car as "a package deal." You can handle either transaction first, but get the first number in writing, then move on to the second number.Brett Affrunti - Car and DriverUltimately, you're dealing with the person across from you, and that salesperson is trying to imagine what a random customer will think when viewing your car. So the obvious items, like curb appeal, that matter to you will matter to the next buyer."There are no top-secret strategies to a high trade value," says Watson. "If you maintain it and keep it clean, chances are you'll earn a much higher return when it's time to trade."➡️ Skip the lot.
