USAA has an excellent car buying service. And, the same service will allow you to accurately value your used car trade in.
I recently purchased a new car, using my 2016 Honda as a trade. USAA saved me thousands off MSRP and I traded the Honda to the same dealer at the amount specified by USAA.
The downside? Since the deal is advertised to a number of dealerships, you might have to travel as far as Orlando. But, there is no hard sell, actually no "sell" at all.
You specify the options, the dealer bids on the sale, initial contact is done by email, then phone.
Easy-peasy.
Oh, and no additional nitrogen ($$$) in your tires, unless you insist
