Way overpriced.

Way overpriced.
We researched consumer reports and found that Schomp was unrealistically over-priced. I was, however, enthused to encounter polite and professional people, but they often lacked knowledge of the vehicles of our interest.
Despite being multiple BMW owners, we had resolved not to purchase there after several friendly visits, but changed our minds when we came across a potential deal on-line. WOW! We saw that the car was unstable at best, but the salespeople would not veer from their over-kbb-value.
The x5 was 4 years old, a loaner, plus 2 owners, and 88k miles. The possible death trap was listed for better than its blue book value considering: driver and passenger doors both locked you in; the back hatch repeatedly failed to shut; it made a squeezing noise when driven; a screw had noticeably gouged the tire; the DVD player did not work; multiple wood panels were cracked and scratched; there were 2 inch white hairs everywhere; and the navigation screen was very difficult to see with the severe wear and tear- negating its purpose altogether. (We were actually asked to climb over the seat to enter and exit)
But trust the good-ol'-sales team to demand more than Kelly blue book value and not waiver.
I believe they lied to me when I was told the vehicle had already cost them over $24k in charges, which was above kbb value. YET, they refused a breakdown as to these costs, and - at the time - had failed to perform any maintenance, or even cleaning. Are they stupid for this acquisition, lying to me, or just believe I am a sucker?
I truly believe the people who rated Schomp as 5 stars did receive great service, but I also believe they were ripped off without knowing. If they can't respect my intelligence, I can't purchase there.
Drew, Chase, Liz, and Josh were all patient, nice, and professional, and have my number: they are free to call me, but don't waste my time unless you can back your numbers, and show me some respect in regards to pricing.
