I wouldn’t try KBB Instant Offers again. They just barfed out a number and sold my info as a lead to several dealers, most of which lowballed me and were absolutely certain that my car wasn’t worth the KBB price even if it was plated in 24 karat gold and the headliner was made out of saffron.
Kargone just elicited a handful of lowball offers from dealers in Maryland.
Eventually I’ll make the time to post a summary of all of my encounters in the thread I linked above.
