Yeah, you do wonder about all this.
Just watched three episodes of "Lazy boys garage"
What a bunch of winkers.
Three cars and on each they made a loss of about £1000. Really clueless. Wonder how it make television. Mind you, for each "auction" the punters were exactly the same. But just watched a prog on a Dodge charger and they did exactly what I would have done, it all worked and they made a profit. So I felt a bit more justified! But they bought in an external gear selector mechanism that was expensive whereas I would have made a new one myself, for peanuts. It is not rocket science. Ditto the "standard" rear spring hangers. Which could have been made from the adjustable ones that came with the car. But the bit about replacing the front wheel bearings and allowing the slack needed for old skool bearings was dead on. Very well explained.
Some of these progs are good some are sh1t and some are OK.
Always liked Car SOS but the money they spent, and the work they farmed out!!!
