Go down Blackstock road, with the mall, Old Navy, etc. on your left. You'll pass the post office and the club on your right. Keep going until you reach a stop sigh and on your right you'll always see a car for sale. There's at least 2 per week and it's a very easy spot to sell. I'm not sure how much the owners of the land charge per sale, but i'm sure it's worth it because the cars always sell. Mark this would be good for you to get rid of that Blazer.
Just thought i'd let you guys know in case you didn't. :)
