Here are 3 tips to get the most value for your trade-in vehicle: 1. Research the trade-in value of your vehicle online using sites like KBB.com and Cars.com to understand what it's truly worth before negotiating with dealerships. 2. When at a dealership, get a written estimate for your trade-in value before discussing the new vehicle purchase to avoid the dealership lowering the trade-in value to increase their profit. 3. If unable to get your desired price from dealerships, consider private sales of your vehicle online through sites like eBay, Craigslist, and Cars.com where buyers may pay more than dealerships.
