We have taken our cars to Courthouse Shell for over 15 years. They are honest, do great repair work at a competitive price, and don't push for unnecessary work. This time when used car's transmission failed, they diagnosed the problem and replaced it in just 3 days, with Nissan dealer parts. Their transmission replacement quote was 20 percent below the local Nissan dealer. Although I have only driven the car 30 miles since picking it up, it is running smooth and like new. Thank you!
