For any mods I do to my car/or anyone elses, I do a ton of research before hand. I try to know every aspect before I actually take on the project.
And as far as the labor side...I love it. I may get pissed at some of the tidious procedures, but then when I am finished I feel this overwhelming joy in knowing that I did the work.
I prefer to be the brains and muscles to the operation.Much better bragging rights.
