First up is the lazy mechanic. This workshop charges to check over your car during a service but doesn’t. The questions you should be asking yourself are have your tyre pressures been adjusted? Do all the lights work? Are there unreported oil leaks?
Most people would fear unnecessary repair. If your mechanic is recommending a repair, they should be able to clearly explain why the repair is needed, what the job involves, what benefits you will get from the repair (e.g. improved safety, reliability etc.) and what the consequences might be if you don’t go ahead with the repair. Don’t be afraid to ask these questions. If you don’t feel you’re getting a straight answer, don’t be scared to seek a second opinion.
Finally, some people feel they are being overcharged. The best way is to ring around for one or two quotes on the recommended repair. But keep in mind that (mostly) you will get what your pay for in terms of workmanship, parts quality and after sales support.
