I just tossed my shit up on Cars.com for now, CL is ridiculous though. Funny enough I bought this same whip off CL, huge mistake, hopefully Cars.com works but if not I'll drop the $90 on the Autotrader listing.
Good choice, in the auto industry we get 10x leads with Cars.com vs AT... Don't assume Cars.com or CL doesn't work if the car doesn't sell though, you can try AT.. But keep in mind we had a used car in like-new condition and low miles, sit on our lot for over a year plus easily.. Even at a cheap price, I think we lost like $8K on it since it sat so long and we had to drop it down. And then there's the buying cycle, where people will call you about the car (while their in the "research stage", and then come try to buy it like 2 months later. Just keep following up with people, no matter how annoying, bug them once a month to see if they'll bump up their price. Even the low ballers, text/e-mail, perhaps they got a bonus at work, or landed a new job, inheritance, move and have cheaper rent, etc.
Ps. have you tried to trade it in yet? Assuming the offers were too low?
Umm what else.. Oh, your ad will get 100x more traffic and eye balls on CL vs. Cars.com (No idea but I did an impression count on our ads on CL and it blew my mind how many people shop it in our market). But highly suggest linking the CL ad to Cars.com as people will click over, they click over to our site all the time.. And once they see the video/full-photos/lead capture form, comments, etc. They convert even better...
Oh in the CL ad:
Make sure you put in the footer. (City, State, Year, Make, Model, (Sedan, truck, SUV), Low Miles, Leather, etc).. Then (Ford, Honda, Toyota, etc list all of them), so it shows up in all the searches.. I sold the shittest, most unknown brand doing that. Would have gotten like 2 searches had I not done that.
But meh... Good luck brah.
