i used to get cold called about my old truck (early 2000s toyota tacoma)
when i sold it (on my own) i stupidly put an ad in an auto classifieds. it's a total scam, just signed myself up for come-ons from auto consignment / financing outfits (sort of how headhunters abuse linkedin). i'm shopping for buyers, not starving fee-based middlemen. ended up making a killing on cl, way way way over blue book. arguably it's value was at an all-time high lol.
i am wondering what make/model is at issue here... it kinda begs the question: if it's a highly desirable model, why would you need help moving it?
EDIT: also, you have a "normal car dealer"? i'm sorta impressed!
By "normal" I meant where I get it serviced (I'm not Hroi who is on a first name basis with everyone at the local Porsche dealership). It isn't anything special it is a previous gen Lexus GS 350.
