Seller won't respond after accepting my price, has listed on craigslist! What's the deal?.

He listed it for 300 more than what he accepted on carguru, no phone just email...

Email him again with your offer. That's all you can do, or find another car.

Would you trust this person to give you an accurate description of the car when he has lied by not following through with the agreement? I wouldn't. There are a lot of good used cars out there you can get instead.
