If by early you mean "slightly before the start of bushiness hours".

Nobody is waking up at 6am to turn wrenches at 7. Yeah, I guess if they start up at 7-8am that puts a damper on your ability to sleep in until 9 on weekdays but is that really something you find yourself wanting to do all that often? An automotive shop sounds a heck of a lot better than any establishment that is open late. I say this as someone who lives baseball throwing distance from a small business that maintains a fleet of excavators and trucks. If you live in a relatively developed area something is going to be making noise, garbage trucks, delivery trucks, nearby construction, etc.
