Why there is not a sticky for shops in the Northwest, idk. This question comes up every few months, with the same debate.
Then again, this seems like something you could do in your garage (if you have one). Speaking of which, outback auto let me come in and use their lift to do some work on my car with a mechanic assisting. I still paid the shop rate for the work. But I walked away with some lessons learned before attempting at home.
