I'm just lucky I have been able to do mine by myself (literally all of it) and the longest it's been down where it wasn't drivable was three days when I put the new motor and trans together and got them in the car.
Also lucky that being the case I think I recently went over what it's worth resale, which I don't ever intend to do.
So with all I have put into it and taking into account it's my only car, AND I don't have car payments, And that my insurance is cheap, I think it's a win all the way around.
I also don't need to put really expensive parts into it, because I don't need them for what the car is built for. (Not a weekend racer)
Mike seems like a good guy, but sometimes it seems he has a case of doesn't know what he doesn't know.

Lots of projects go like his did, but it's just a car and lots of money isn't the only solution a lot of the time.
