Z is intense when it comes to unnecessary servicein my opinion, most dealers are crap. weather it be sales or service it's all about getting as much money as possible. Sure there are some good ones, but they're not common.
Sales, it's all about getting as much as possible. They don't usually have much knowledge about what they're selling and often misrepresent the car. But you can be damn sure they're going to push that extended warranty. I had one tell me what a big favor he was doing by offering $200 of the sticker price of a $26k car.
Service is much the same, sell extra crap that isn't necessary. $80 for tossing injector cleaner into the gas tank that you didn't need anyway. Deny warranty claims. Replace parts like belts and air filters before they need it. And then there's my favorite: perform a "diagnosis" only to not find the problem but charge you for it anyway. Give us more to diagnose it!
I once did some work on my mom's car few years back as a birthday gift. Coolant flush, trans flush with new filter, new timing belt with new pullies and replaced the water pump. Less than 6 months later she had to go to the dealer and the tech tells her she needs a new timing belt RIGHT NOW before it breaks and blows the engine! He didn't like being called on his bullshit.
There's only one solution. Your knowledge. With sales, know what a reasonable price is for the car ahead of time. Research the shit out of it so you're not relying on the sales idiot. Take control of the sales process, don't let them lead you. When I go looking for a car, I tell them exactly what I want. Not the other way around.
With service, try to diagnose what you can on your own. Know what maintenance needs to be done and what doesn't. Don't get bullied into extra stuff on the spot without doing some research first. Again, lead the process. They're all taught to control the sale weather it be purchase or service. Take that away from them and it'll go much better for you.
Ok can't argue with that one, except it's more about time for me at this point in my life. I want any maintenance or repair job done right the first time to the highest standards reasonably possible. Not many shops are willing to do that unfortunately. But with me working a pretty awful continental 12 hr shift schedule and two young children at home, I'm not interested in wasting time.Not Cheap - You want most bang for your $$
