Alta Infiniti is by far one of the worst dealers you could possibly deal with. They're a facade (All looks no brains). Nice building, stupid people. Us members here know more about the car than their most experienced mechanic. I've been there enough times and had enough issues with them that I had more knowledge about.
I made them look stupid in front of customers who were having issues with their cars after they took my advice and I don't work there!!! Ever since they revamped their building, the parts department is in the closet literally. They don't want you to fix your car, they want you to come in and believe parts no longer exists so you can give them your month's salary.
The service people in there are just clueless about anything and if you ask them something technical, they clearly have no idea what they're saying yet they act like they know it all.
If you like your car, go somewhere else and make sure you do your research on here. The best people I ever dealt with are at Dixie 401 Nissan. Yes Nissan because that group of people want your business and strive for it. Not like Infiniti, all show :P
