The cars just provide the vehicle so to speak to show you the main people that work at Counts Customs; with nearly always 2 cars / bikes per episode plus the Danny's pulling over people to ask about their cars & the shenanigans of Mike & Roli, all packed into just 20+ minutes, there's not much time to show you the build, just the receipt of the car/bike needing the improvement, the haggle on price and the delivery.
Whether it's all set up or not, Counting Cars shows Danny's real appreciation of the automobile, if Joe Public when pulled over "randomly" to talk but refuses to sell Danny their car, the excitement Danny shows that he got to talk about "Car X" with them does seem genuine.
Throw in the odd celebrity like Cassandra Peterson or Rob Zombie and you've an interesting show. But I'd love to see Elon Musk walk in with a job for them, lol.
The only off-putting part is the disdain Danny shows for Mike which is, I hope, really just put on for the show because Mike is an outstanding airbrush artist. Or if Mike is really such a goofball, then fair enough, but he'd still be my go-to guy for anything requiring customized airbrush artwork.
Finally, the show does portray Danny as a real pushover when it comes to people who have served in the military or are creating a memorial of some sort; in those instances, he doesn't deliver a car/bike, he delivers a dream. And in those moments, the shows succeeds and brings it into line with something like the UK show, Car SOS.
Hope Season 5 gets the go ahead.
