Q: Do you provide a warranty on repairs? A: Reputable auto repair shops typically back their labor and parts with a warranty — commonly 12 months or 12,000 miles — so be sure to ask about the specific coverage when you bring in your vehicle. Q: How long will my repair take? A: Turnaround time depends on the service needed — oil changes and brake jobs are often same-day, while more complex engine or transmission work may require a few days, especially if parts need to be ordered. Q: Should I get multiple estimates for a big repair? A: For major repairs, getting two to three estimates is always smart. A trustworthy shop will welcome the comparison and provide a detailed written estimate so you know exactly what you're paying for.
