Online resource for used car values

Yo. Looking to buy a car, see something I like enough. E

2016 Ford escape titanium. All features plus sunroof, 40k mi, got the price to $15,500. Where are the car guys here?

 

I could go for another model, but fixed on not going up in price, and escape works for the next 10 years for hockey gear transport for kids.
