BMW of Bridgeport

I purchased a CPO 2011 Z4 on March 5. 2016. The next day I discovered an absolutely broken and half missing hinge in the trunk compartment, called the dealer and 10 days later their solution was for me to come in and have their service department try to secure it with some bolts or screws. They said the part was to expensive to replace. Everyone there was to busy to pay attention from the get go Answered all my questions with what I wanted to hear. They tried to sell me a $1489.00 extended warranty on the run on flats that this car was supposted to have- only problem is that when I had the car into another BMW dealer for a check up just three weeks after I purchase it, I was informed my car didn't have run on flat tires. Good thing I didn't purchase the insurance. They also had me pay New York State sales tax the day I purchased but when I went to my motor vehicle department I had to pay it again as CT is not authorized to collect NY sales tax. I can hardly believe Bridgeport didn't know that. Additionally while having another bmw dealer look my new car over they found 3 bent rims and I had to pay $337.50 for a software update to stop the car from a cold start rough idle. I was told that this software up date has been available for at least a year. Guess Bridgeport just didn't want to install it. I punched this car 34 days ago. I have a broken/ missing hinge in my trunk compartment which impedes the automatic hard tops functioning, NO run on flat tires ON three bent rims and outdated soft ware. Honestly, they couldn't even get the car detailed correctly. When I got home I detailed it myself and found 2 pens, a doctors appointment reminder card for the pervious owner and one store receipt. REALLY? It's only half a car, a two seater convertible. I have filed a formal complaint with BMW of North America. I would not recommend this dealership to anyone for anything and I do not believe BMW of NA is going to allow their representatives to act in the manor they Bridgeport did. I am a reasonable, honest and patient person. Had I wanted to be treated the way BMW of Bridgeport CT treated me I could have bought my car from any corner auto-mart. I fully expected to pay more for this car at a BMW dealership but I expected some integrity in exchange.
