Note a couple of those reviews are very positive. Those positive reviews are most likely fake 'plants' placed there by the dealership staff. Fake reviews are like toupees. If you know what to look for, they are easy to spot.
I have a management, marketing and sales background and, imo, the fundamental weakness in the retail auto industry is the dealer. Most dealers engage in retail business and sales practices that simply would not be tolerated in most other industries.
Auto manufacturers go to great lengths to design and market competitve cars. It's a shame that the typical dealer ruins much of that competitve advantage and has to make the average purchase decision feel like such a sleazy, unpleasant affair.
Imo most dealers know how to treat customers properly. Most commercial and fleet customers are treated with far more honesty, integrity and respect than the typical consumer.
