I'm looking to sell a 2009 Camry with about 125k miles. Although it drives fine, the engine recently started leaking oil, plus it has some minor cosmetic dents, etc. Kelley BB says it's worth about $4100, but I'm not getting offers anywhere near that from Carvana, Rodo, Algo, etc. Will a dealer give me more than they're offering when doing a trade-in, or any other options I should look into to maximize what I get for it?
