Great service, and receptionist--who goes above and beyond her desk-job. Other than that, I felt great leaving the place, feeling as though I was in good hands.. but what bothered me the most--enough to revise my review--was the fact that:

my initial sole issue with my car was eventually summarized as a $10 hose that needed to be replaced (ultimately by a third party), but was told by Paragon's owner that it would cost $400 to fix, along with diagnosing me with many other potential issues which I paid to have "fixed."

Background story: I came to this place because I had an intermittent sound issue that was annoying me when starting up the car..just an obnoxious hissing sound that would go away after a few minutes of driving. After reading about Paragon on yelp, I arrived and was charged about $300 to fix other non-related issues, and was told my hissing noise was a temporary fix and as a "FIRST STEP RESOLUTION" because I was told that the hissing noise would most likely return, but to wait a week until it did, and to then make an appointment for the solution and pay their $$$ cost to have it solved.

The following day AFTER getting my car back from Paragon, my hissing sound was back!! My friend who owns and works on specific cars like mine (e46 m3's) took a look at my car and diagnosed/healed my sound issue in less than 2 minutes. He yanked out a random hose from my engine, walked back to his car, yanked out his same hose and replaced mine with his--less time than it takes to take a really quick dump my entire sound issue was solved! With a $10 dollar hose, from a "non-specialist" who doesn't work at Paragon Automotive!

I drove straight to Paragon after the quick/amazing/WTF fix, summarized my issue to the owner, who turned bright cherry red. When I showed up, parked my car, told someone my story, was checked out by a mechanic to varify my story, I was given/told..........awkward silence/laughter/greetings and salutations and see you later/OMG/I hope you don't write about this on Yelp. I drove home knowing I paid them to fix non-related issues along with having almost been raped to fix a $10 dollar hose that was my original problem.

Update: Thinking back, I realize that visiting this place was exactly like visiting the BMW dealership, except I was treated with more respect and wasn't just a number in line, while being given the whole nine yards of deception with plenty of smiles and trust me's.This place may be a cheaper replica of your BMW dealership, as they have all worked at the dealership but started their own business together, but it all ends there.. abruptly.. when you realize that you're just about to be had into thinking this is the same service at a cheaper price.

DECEPTION IS DECEPTION, but with experience dressed in different clothing after you come here with hindsight and luck/experience on your side.
