I agree with the above. Review youtube videos and understand what tools you might need. I'd also recommend going to 1A Auto's website. They sell parts, and I sometimes buy parts from them, but they also have really well done videos on how to do the work.
In the past, I've reached out to dealers for quotes to do work, and have them break it down to parts, labor and number of hours. I would assume that doing it myself would take at least 2x the amount of time it would take them due to facilities, tools, experience, etc. Then I dig into how much parts would cost me if I did it.
Finally, I look into the cost of what additional tools I might need to buy. I usually consider only half the cost of the tools in my DIY vs Pay others analysis, because I consider the tools an asset that I get to keep and use in the future.
When I was younger, I usually always broke even or better including the cost of tools. Now I've got almost everything necessary when a 'typical' repair job comes up, and there's no tool cost associated. Also, labor rates are crazy now (~$100/hr last I checked), so that makes it alot easier to justify doing jobs myself.
Best of luck, Neil
