If they offer you a lifetime brake warranty at an additional cost ask the store manager to explain the warranty in detail. There are so many brake components that are not covered. I will talk a little further in upcoming posts.
Exhaust shops also most of the time offers a free inspection. If you think your car sounds a little louder than normal they will inspect your muffler, exhaust pipes, catalytic converter, and hangers and give you a free estimate.
I would bring another estimate from another shop and ask if they can beat this estimate. If you catch them on a slow day, no or little cars in the parking lot, they might work with you. You'll find this strategy will work with any repair, you need.
Another important point to remember, most big auto parts chains such as Advance Auto Parts offer free alternator, starter, and battery checks. Going there first could save you a diagnostic check out fee someplace else.
