Penske Lincoln of La Mesa

This is the worst experience I had in a long time. After waiting 4 months my Aviator GT I finally received a call from the Sales manager (I never had answers to my questions during the wait, I received all the information about my car thru the blueoval forum from the Ford guys, those people are amazing and this forum is a big help). This Thursday the Sales Manager told me that my car had scratches from the transport and asked me to come on Monday. Monday noon I was here , nothing has been done. Seeing that I was angry he told me to come back at four. Before that we had to do the paperwork. I signed a lot of documents plus a credit application, I was surprised because I paid cash, they wanted my incomes and bank information, I was puzzled and asked why, at the end they say : "ok write down your name and sign, that's it".
Then I went to the financial department where a lady asked a lot of signatures and offered me a lot of options. The first one was an 995$ alarm , I asked many times if the car had an alarm, nobody was able to answer me, so I accepted the alarm, the lady told me that I will be contacted in the next 2 days and somebody will show up to my place to do the installation. It's now 20 days and I saw nothing coming , no need to say that when I discovered that the car HAD an alarm (indoor and outdoor sensors) I tried to contact the lady and left messages but as always no answer. After that I returned to my hotel to be prepared for the 4pm delivery. At 4 I discovered the most crappy job ever, they put some paint on the scratches , horrible. Seeing me so horrified the Sales Manager asked me to bring back the car for two days. The round trip to the dealer is 5 hours plus two hotel nights, I asked him if the Lincoln dealer near my home could do the painting, he said yes. Another thing : when I built my car on the Lincoln site I chose an accessory (front and rear dash cams), during the four months waiting for my car I asked who was doing the installation, I never had an answer. So when I had the Sales Manger on the phone the Thursday I asked him the same question , he had to tell me something, he said that he asked the workshop and the cost could be 750$, I said OK. BUT on Monday he said something different : first he didn't have the accessory and second I would be a guinea pig because nobody did the installation before and he didn't recommend it !!!! just FYI I found near my home a garage who is doing a lot of modifications on cars and charge 400$ to do the installation with no visible cables.
for the delivery of a 90,000.00$ car I had no explanation, not even a little drive with somebody to show me the basics.
Now probably you would ask why I chose Lincoln La Mesa so far away from my place ? I checked with a lot of dealers and they offered me a very good discount (5000$ difference with the Palm Springs dealer). I understand now but maybe I am wrong why they did that. I received the discount from the Witt family and they sold the dealership to Penske Jr, just assuming not sure.
But now I deeply regret no to have chosen the Palm Springs dealer because the people there are very helpful and nice, they first tried to join Penske Lincoln with no success (of course) and left messages because they needed the paper from the carrier to do the paint job. The next day they call me that everything was OK. Now the car has been fixed and is pristine.
So this an awful experience, and I'm just thinking maybe it's because I'm French and they don't like European , I don't know, I hope not and maybe it's because I'm not American and I see thing differently, BUT my American friend was with me and she was horrified by the situation and I had to calm her.

Just to finish this I know that the name Penske is very prestigious so I am really surprised to find their people so incompetent , something has to be done but for now stay away from that dealer.
