A truly professional auto body shop will give you options to consider for your repair. Rather than insisting upon replacing all of the damaged components with entirely brand new parts, the service writer or manager presents you with an estimate that outlines the cost of using guaranteed reconditioned parts. Some auto body service managers are hesitant to guarantee any work done with other than new parts, even if the reconditioned parts themselves are guaranteed. In those cases, the shop should present you with an option of repairing the parts, rather than purchasing new. Obviously, repair is not always possible or cost-efficient if the damage is severe enough or the labor required would make repair more expensive than replacement.
