Review is specifically for their parts department. As an owner of several Toyota vehicles (one over 45 years old) Camelback's parts team is well-educated and knows how to find parts that Toyota still offers, but may not come up under a 'standard' search.
Combined with Toyota's amazing level of interchangeability between years (there are parts from 1983 that fit vehicles from 1968) and having a good parts staff is essential. Camelback has these people. I have not used them for service, but when the need comes up, especially for an older Land Cruisers, I will use them.
In addition, if you know your part number, their online portal is perfect and the prices are as good as they get. Easy to hit the right dollar amount for free shipping too. I know of more than a few vintage Toyota guys that don't live in Phoenix (or Arizona), but will source parts from Camelback Toyota.
