I too am in Colorado. I consider the three biggest Porsche dealers here as Porsche of Colorado Springs, Prestige Imports and Stevenson Imports. The person I liked a Stevinson Imports left and let me say this, the people that are left, will not care about you at all unless you're paying over and doing the work for them. Absolutely poor customer service, so much so that I hated the 718C my first time around due to the sales rep. Their knowledge of the cars is all on the sticker and website, they'll tell you the drove and compared them to competition, but when you ask for exact details they'll just say Porsche always drives better. Not only that, the finance manager is an ass.
Prestige Imports customer service is excellent and they know their stuff. They will go the extra distance to make you feel valued, but price will not budge a single penny. If you don't mind this then this is the place for you.
Porsche of Colorado Springs, I encourage people to go to their website just to browse to get a sense of how they differ from the previous two. Not only is the location well built and inventory sweet, the staff was extremely knowledgable and transparent. I worked with Joe during my search and it was exactly what you'd expect and want from someone helping you with your decision. Instead of being pressured to spend more or move up in model/price, everything was realistic and the feedback was valuable. I was given honest advice about the car I drove and bought, versus the other options on the lot when I asked about them. To me that was important because he took what I said I wanted and was looking for and delivered on that.
While I can only take the word of the person, it is VERY different when someone sells you a Porsche because it's their paycheck, versus someone invested in the brand and is also a customer.
