"Here" is what Sperry mentioned in his first reply, Cory at Nissan of Reno. Sorry, thought everybody knew that was me!
What you're missing is: Repair shops go by what's called a "flat rate manual" that determines how much they charge for each job. According to the manual, replacing coil springs on an Impreza is 2.0 hours per corner. At around $100 per hour, that's actually nearly $800 at standard pricing. NOW, I have the tools and experience to do that job a LOT faster than that 2 hours per corner, and that's how I make my money. I've spent over 35k on tools, and 20k on my education, but I sure as hell don't make a lot hourly, so the ability to do a job MUCH faster than what that manual says is how I bring home decent money. The $400 that I quoted you is my personal way of taking care of club members here on SECCS, because I know I can knock that shit out pretty quick.
