I would comfortably call this a "mixed bag". It has its moments, including some really nice transformations, but you have to sift through a lot of average content. It's like someone wanted to directly mirror a standard TV car show, but without any.. magic.

It includes:
* Every time they plan on selling a car, they'll say one price on the phone, then when they actually show off the car they'll bump the price significantly and hope the buyer goes for it. If the buyer says no, they'll ask for something else in return, or move on to the next person. They call this "making a deal", but it just seems super disingenuous to me.
* They keep talking about "a big payday", but [spoiler]you won't see one in either season[/spoiler]
* In terms of actual car modifications: you'll see them find/receive the car, the initial teardown, the planning stage, a bit of scattered work here and there, and then it'll **always** jump to a quick spraypaint and then straight to a finished build, making it hard to see how they went from A to B. This is **very** unsatisfying and was a common theme throughout the show
* As mentioned in another review, they repeat the same things a lot. At the start of an episode, directly after the intro, and then every time someone says something while working, they repeat it sitting in front of the camera. If they're in the middle of working on a specific build, they'll walk you through the planned build multiple times, as if you weren't watching 15 minutes before. This is a Netflix show, not on TV where you might miss part of it.
* I actually feel that by [spoiler]splitting into two garages[/spoiler] for Season 2 [spoiler]they actually lost some of the overall charm because they were no longer a single team all coordinating with each other all the time[/spoiler]

Overall, it's an alright way to kill time, has some really fancy builds, and you won't hate yourself after it. I wouldn't watch a third season though.
