Tune up is an old term irrelevant to modern vehicles in most aspects. So, when you call a shop and say you need a tune up, you are going to get a different answer depending on the shop.
Your vehicle is in the shop and you have questions that you believe only your mechanic can answer. You give him a call but he’s unavailable. What’s the deal? Why does my mechanic say he is occupied?
Building a relationship with your mechanic is important because someone who is familiar with your vehicle, its maintenance and repair history, and who knows you will be more likely to take the greatest care of you and your car. This trusting relationship will reduce the stress of the inevitable major repair and you’ll be able to drive down the road confident in your vehicle’s performance and safety.
