Welcome to the group
Looks like book value for your Suburban is around $8k, what price range were you looking for in an SSR, miles, color, any special options that you need/want on it, etc.... or are you totally open to anything? You mentioned a lot about what you have but left out a few areas that might help your quest.
Might want to contact Christo at 832-446-4000 or
cthomas@nfhyundai.com or just view the website at
http://nfhyundia.com as they are in Houston TX and have a TON of SSR's in stock. Many people have bought and sold from them with good experiences.
Good luck in the search
