Two reasons: I-CAR Gold Class certification and a lifetime warranty. Most shops in the South Bay and Torrance area aren't I-CAR Gold Class certified — it requires ongoing training and investment that many shops don't make. For 15 minutes of driving, you get a significantly higher standard of repair and the peace of mind of a lifetime guarantee.
