The quality of the pitch is only marginally related to the two most important questions about the company: Is it a good market? And will this company be a leader in this market?

Agree, maybe I am just being a curmudgeon today, but the kind of companies that TechCrunch chooses for Disrupt as a general rule of thumb, don't excite me.

It is a good idea though, peer-to-peer anything is the new hotness.

Peer-to-what-now? People in YourMechanic's market used to have to comb through useless Yelp ratings to find a place to take their cars to and leave them for a day or 3 to have basic repairs done. Now they can type some things into their Googles and have their cars fixed at home.

As a card carrying member of the "160k miles, last 20k with the check-engine light on" club, this is the best thing ever and I can't wait for them to get it to Chicago.

I'm amazed at the number of people who drive 20,000 miles with the check-engine light on, despite being able to financially afford to keep their car in good working order.

Your car's maintenance can easily become a life or death issue if you lose engine power on the highway, or far worse, lose brakes or a wheel. You wouldn't go to Dr. Nick Riviera would you?

YourMechanic hasn't magically replaced the trust system. It's simply another competitor offering its services...if you trust them. It only takes one bad mechanic to poison the well with customers.

YourMechanic hasn't reduced the time it takes to perform basic repairs. The only practical difference is where the repair takes place and that you can schedule it over the web instead of over the phone. Existing mechanics already offer at-home repairs (albeit, at significantly higher rates than in-shop repairs) so YourMechanic's "innovation" is really just offering existing concierge mechanic services for a lower price.

Here's the thing: any mechanic worth his oil doesn't have the free time to drive to customers to perform repairs. He may have employees drive out to customers to pick up cars on his behalf, but he will remain back at the shop. Thus, YourMechanic will ultimately attract the types of mechanics who don't have the skills to set up their own fixed locations, i.e., mechanics who are mostly definitely not the cream of the crop.

That's an interesting observation that made me slightly revise my opinion of the concept YourMechanic (formerly extremely bullish). My garage charges labor at $125 per hour, which is not the cost to the owner (I'm sure the owner pays his mechanics $50 or less). Nevertheless, a mechanic has to pick me up and drop me off at the train station, which is not that much worse than coming to my house.

Incidentally, I'd never use an at-home service, even though it's very inconvenient for me to drop off my car at the garage, because the quality of car repair can be a life-or-death issue, so I'd rather that my mechanics have all the tools and equipment (car lift, adequate lighting, etc.) they need right at their disposal instead of being tempted to cut corners.
