No better feeling though! Especially when running the numbers post-fix (insert CS joke here) and comparing to shop quotes. I keep spreadsheets for two cars and an older jet ski and I've saved ~$12k this year alone by wrenching solo assuming $100/hr = standard labor rate. I've learned a TON of cross-functional skills, have full control over the parts and repair, and it's just a feel-good way to step away from my desk when things slow down at work.
I remind myself of the the 5-digit savings whenever I'm in line at Harbor Freight... which is often.
