Just throwing this out there, the 350z is one of the most deadly cars on the road (specifically model years 2005-2008). Not because it's an unsafe vehicle, mind you. It's one of the most deadly cars on the road because it was, and still is, an insanely affordable sport car with enough power to allow immature and inexperienced drivers to easily exceed their driving skills and rational thought skills.

The long and short of it, a 350z is WAAAY too much car for a 17 year old male. Also, since insurance views a 17 year old that only has 1-3 years driving experience as a smooth brained dolt you will be paying through the nose even for liability because they know you'll end up driving your car through someone's front porch or crashing into 5 other cars as you fail to control the power.

Now that we are past the " you really shouldn't buy anything faster than a base model Civic", all the wage questions you have depends on where you live. It could be as low as $7.25/hr (about half the states) or it could be as high as $15.74 (Washington) and it could even depend on the city or county you are in within the state. Unskilled labor is and should be paid at a low amount fitting the work being performed.

If you want to fast track your hourly compensation, look into apprenticeships for something in the trades like road construction (~$15/hr), plumbing (~$22/hr), electrician ($23/hr), etc. Don't be surprised if you get offered less of an hourly rate than I posted, that's averaged across the USA and you'll make less at a small town company than you would in a big city.
