the last few cars ive sold off CL have gone to the first person who actually showed up to look at the car. That being said, I will usually make an apointment with someone and have them call me 15min before they are going to show. No call, I keep doing whatever I was doing. CL does have a lot of flakes, but the people who I have delt with have been pleasant. Ive purchaced cars, washer/dryer, motorcycles, and other misc items. Its been good to me.
I usually dont 'chase' potential buyers, if they want the car bad enough, they can email me or call.
