I'm better at building computers than working on something at this level with my car, plus the computer tools will not work with my car
It's just the cost of convenience. Plus, the person working on my car is a Nissan master tech. They can get this thing done in about 2 days. If anything, they'll have quick access to tools and parts. It'll be nice to get the car running well in one week versus several weeks dealing with hiccups, ordering parts, troubleshooting, etc.
