No, but you can make more than the average flat rate schmuck working at Kia.
My job is not the end all be all but if I could just jump to the highest paying gig in my career field then I would go right ahead an do it.

Average schmo mechanics dont make much. Even experienced fellers dont make that much. I could tell you just how much I made but that would not solve anything. I do make more than a service manager at the local Chevy/GMC dealership though. No, this is not diesel marine mechanic wages but it is a healthy sum for someone with a college degree in anything but auto/technical studies. Yeah, I have a degree but not in auto/diesel. I took a few classes and raped the Snap On SEP but I do not have an auto related degree.
You cannot just work at any golf course and make this kind of money though. Like I said, I work at a recreational resort with both golf course maintenence equipment and facilities maintenece equipment including cars, trucks, vans, forklifts, all kinds of small engines, diesel generators and the like. You need to be a REAL MECHANIC to work here not just a PARTS SWAPPER. If the part is expensive or unavailable, you make one. If your hydraulic cylinders on your lift are shot you rebuild them. If a mower reel needs sharpening you sharpen it. If there is problem regarding anything mechanical you fix it. Period.
No I do not get 6 figures. If you do, then you are one of the lucky ones. I know it is not unheard of so if you say so, I will believe you. The unlikely dream of many of my auto classmates was to work at a Mercedes or Porsche dealership one day where it was said 6 figures was common. I personally think it is possible after about 10 years of experience.
YMMV
