Got a letter from the AQMD, they want to test my car for emissions compliance. They will have it for 2 to 3 weeks, give me a free rental and pay me $500. They will also pick up and drop off at my house, return my car washed and with a full tank of gas. This is to monitor the long term performance of emissions systems to see if they are up to snuff after 5 years. The car is 2008 smart.
