Prompt service, very helpful in diagnosing whether I had the right parts. Have great advice on when to change the parts again. Would recommend to anyone who needs mechanic support
Needed a car battery changed. Set up the appointment and they had someone out the very next day. The mechanic did a great job making it happen. Very much appreciated.
From start to finish the whole process was smooth and easy. The website was easy to navigate and when I called for additional assistance I was helped immediately and there was no pushing me to purchase additional services. The mechanics arrived on time, asked good questions, and worked quickly. Very polite and helpful. I was glad I chose this company.
Had a leaky fuel rail, tech came out same day and fixed it asap, very professional and very easy to get work done.
Very skilled and prompt on site and the truck starts up fine with new starter- highly recommend him for future repairs
Instant Car fix saved the day, the tech was knowledgeable and efficient and knew exactly what was needed. Definitely recommend for my BMW F32.
