I was very pleased today with Smog Depot on N Cedros in Solana Beach. I had searched online for smog test centers, found this one on smogtips.com and got a $15 off coupon. I read 2 Yelp reviews from 2011 -- one 5-star and one 1-star. I was concerned about the price issue, so I called and verified the total cost (including the filing fees to DMV). The net cost to me was $55.20 and the work was done within about 20 minutes. Net-net, I was pleased.
