Understanding Repair Costs

Repair costs are generally split between parts and labor. According to industry data, labor often accounts for more than half of a repair bill, and rates vary significantly depending on whether you visit an independent shop or a franchise dealership. By tracking your own maintenance history in QuackAuto, you can identify patterns in your vehicle's performance and avoid the "surprise" factor of major repairs.
