I had an issue trying to get my 1998 Jeep to pass the smog inspection. my mechanic fixed the car but I had to drive it 100 miles to reset the computer. Cathy advised me throughout the process, checked the computer to see that it was ready for the smog test and made the experience much less painful! Great, old-fashioned customer service and delivered on a timely basis. I highly recommend Dhillon motorsports For smog testing and other mechanical needs of your vehicles. We have seven cars in our family. We will be regular customers
