He's a tool, a dangerous tool, which is why he gets money thrown at him, just like the orange monkey in casablanca.
I suppose he IS dangerous to the automotive industry, and as a consumer that's just fine with me. It's a very sleazy and unscrupulous industry whether car makers or service and repair the carp he uncovers and reveals is priceless to consumers.
You would take your vehicle to a guy that works in his backyard on dirt/gravel? I don't see how he can take pride in his work when his work area is a total pigsty?
He basically can't do any major repairs, Probably the reason he talks $h!t about any job/repair that requires an actual facility & equipment to perform?
My cousin's shop wasn't so different, and that dude was a magician with older cars. Newer cars, mainly a body work magician, but older stuff? He was running 11's@120+ in the 1970's in his daily drivers. Timeslips, pictures, everything to prove it, not just running his mouth. Many people with pig sty work areas know EXACTLY where things are in their heap of mess. It may not be my style or yours, but I've seen too many rogue geniuses who work in pig stys to discount them.
One of the best mechanics I knew never worked in a shop with a lift, and it often appeared to be a mess.
Another mechanic had one of the most elaborate Snap-on set-ups I've ever seen. And he was a hack.
Don't judge a book by it's cover.
Can't comment on this Scotty guy, as I've only watched part of one video.
