and CBI (Idaho) and Equipt (Utah) is also contracted to help build your GX460 concept vehicle....you've arrived.

So no, their aren't exactly "rankings", but some of the highest talked about shops and parts dealers are in SLC and Idaho. I'd also consider OTRAMM to be up there, but they are south of Washington DC and obviously never been in their shop....but I use their youtube videos and they know their stuff.

GBR (formerly Great Basin Rovers, until Land Rover told them not to use "rover" in their name) is arguably one of the best classic Rover shops in the US and it's also in SLC. It's highly regarded in Land Rover circles.

You have people from all over the country using the above shops for their parts and maintenance kits, or even shipping and delivering vehicles to have them worked on. I know, at least with Cruiser Outfitters, that they are networked with other local cruiser and Toyota shops for a lot of the maintenance too, so they know who to trust as they have a reputation to keep.

So yeah, I think it's a fair assessment to claim that some of the best Toyota SUV shops in North America (if not the world) are on the Wasatch Front.
