I had a car that they serviced for 400k miles and it was still running when I got rid of it. My next car has 150k miles. They also service my wife's car, which has 200k miles on it. We have been using them altogether for 15 years and over 750k miles worth of service. I am very happy with North County Import Specialists. Glenn always lets me know when things need done right away and when they can be put off for a little while. He is good to work with and he does good work.
