Yes I agree it's an interesting concept, however it may be flawed.
If I'm reading correctly, you buy a 70 Cuda and get all inclusive labour for one agreed and set price of $70K.
Obviously parts are extra....
But lets break down the $70K
Lets say the Cuda is a solid project to start with...average $20K
That leaves $50K to cover ALL the labour....apparently it doesn't matter how radical you want it, it's covered.
To quote " it's very easy to have 1500 hours in a good build"
$50K / 1500 = $33.34/hr
To quote "average shop is $50-$90"
Tells me they are less then average to begin with.
"a great job took us 3836 hours" or $13/hr ...
I get most crooked shops exaggerate the amount of hours to charge you more then they quoted, but these guys have locked in a labour quote....So how do they deal with overage ? Start cutting corners ? Start doubling the price of the parts ? I really don't think they will be the ones losing in the end.
