Sure, he could part it out, but, what's the fun in that? Seriously, If I had acres of property and vehicles that were given to me, I'd do the same thing... Maybe not with an IDI F350, but, a rusty old beater car, sure, I'll beat it into submission and then sell it off for scrap metal, no problems there.
If you think that's horrible, you put entirely too much value on what is little more than scrap metal that still runs. There is a very large difference between a vehicle of value, and something that is basically junk but might have some fun left in it and was FREE.
It's not like he's turning around and trying to sell this stuff.
If you watch his other videos, you will see that Dave is an accomplished mechanic, and generally a pretty normal kind of guy. The cold start videos are at the request of his viewers, you'd be surprised how many people on you tube ask for that sort of stuff.
As for if it hadn't started, if you watch some of his other videos, you'd see that if it doesn't start, it doesn't start, might get some colourfull comments about it not starting, but, that's about it.
My 6.9 truck is going to see a much worse beating this summer than that one ever has, since my 460 is wounded, and I'm not working, the 6.9 is getting the Boggers and going four wheeling. It WILL be getting a snorkel.
