Hi guys. Just wanted to post a big update here. First of all, I don't know if many of you know this, but there are a TON of forums linking to this thread, with discussions of their own. S197 forum, MustangCollective, even things as out there as VW forums and the FocalJet forums. I have many car club/mustang owner friends and they are all furious at how this went down, especially knowing how I treat my car. Many people from many different forums have so far called their local dealership, called Ford, sent emails, and raised huge awareness of how big this is online. Ford and the dealership cannot ignore this, and hopefully this will make them think twice before doing this ever again.
So, on to a bit of good news.
-I got the car checked for "Abuse" codes at a dealership I will not name because I have not obtained their permission. No abuse codes were thrown from Columbia Ford's Sunday test drive. Abuse codes are pretty extreme flags for the computer, including extended bouncing off the rev limiter, etc.
-Through another forum, I ended up talking to the GM at Hoffman Ford of East Hartford. Even having never done a bit of business with him, he set me up immediately with his service manager and allowed me to sit with a senior tech and go over my concerns with the car. That is after walking right in, by the way. Columbia couldn't even guarantee when their "mustang-pro" service techs could be free that day. Shows how critical the issue was to them.
The service tech's conclusion was I have a healthy mustang with normal noise levels and excellent clutch engagement. He does not think the flywheel is glazed or there is any other immediate issue. His words were, "document, document, document it all, and if you have a problem, then you can talk about a replacement covered by someone. But no reason to worry now." So either I had an extremely quiet Mustang before....or I was hypersensitive to sounds after the Sunday Episode.

THANK YOU SWEET BABY JESUS.
So, on to the consumer lesson-plan of the day:
OBVIOUS LESSON #1: Never give your keys to the salesman unless you have considered the worst possible scenario, such as gremlins being fed chicken in your interior, and are OK with that happening.
OBVIOUS LESSON #2: Despite abiding by lesson #1, follow your keys around like a lost puppy dog.
OBVIOUS LESSON #3: Never leave the dealership. Throw things in the dirt, kick rocks outside, jog around the lot, grab your stress ball from the car...whatever you have to do to calm down. But stay there and make them stay there until it is right.
OBVIOUS LESSON #4: Bring a friend. If I didn't have my friend on Sunday with me to witness the stalls and clutch, etc...I would have NO leg to stand on and the dealership could've easily steamrolled over my complaints. I saw how easy it was to come up with "witnesses"
OBVIOUS LESSON #5: Don't get walked on. If I was smart I would have taken my keys and gone after they came back from the test drive. It didn't help my situation that we sat down in the dealership for another half hour. For someone whose clutch was smoked to a lesser degree, they might not even have noticed.....
Now for dealer lesson time:
OBVIOUS DEALER LESSON #1: Always ask to take a test drive. I don't care if it is a trade-in and it is very obvious you have to drive it. Ask. Cars are generally second only to houses on the list of most expensive thing a person owns. Don't treat it like your right to drive them, or you'll find that your customer learns THEIR right to go elsewhere PRETTY DAMN QUICK. (Though not in my case.)
OBVIOUS DEALER LESSON #2: If you do not follow OBVIOUS DEALER LESSON #1, then APOLOGIZE. By being defensive and denying the validity of the customer's complaint, you ESCALATE THE SITUATION.
OBVIOUS DEALER LESSON #3: This could all have been put to bed Monday had I not been lied to. An apology from Dale would've smoothed things over further. Instead, I was told that I was essentially full of S**T, but would I like to get my car looked at there anyways? Because, after telling me they had 3 false witnesses, they would CERTAINLY report any damage they found. Or just use the time on the lift to take more pictures of my car and threaten to send it in to ford as proof of abuse. Which brings me to....
OBVIOUS DEALER LESSON #4: Do not play CYA! Here I am still at the dealership, waiting to work it out, and he's taking pictures of my car and tire tread. Why? Because he possibly thinks I will not be satisfied with his answers? That he has already decided he has reached the end of what he is willing to do for the situation?
OBVIOUS DEALER LESSON #5: When you have a customer that has major concerns about damage done to their car by an unauthorized test drive from an employee, don't toss that customer on the waiting list. If you have techs that are "Mustang Pros", pull them off whatever the heck they are on and put them on the car! Don't tell that customer that they should be available shortly. What is at the head of that waiting line? A blown engine because of a test drive? Why should I even have to be asking if this can be done immediately instead of "In the next day or two"?
Finding out my Mustang is considered fine by two other dealerships definitely tempers all of my concerns about possible damage done on the test drive. Perhaps a mod can even remove the reference from the thread title.
My concerns with how I was treated remain. Why lie? It is such a stupid thing to lie about, and it instantly threw out any chance of mending bridges. I'd say I was MORE than patient and MORE than willing to work with this guy. If he thinks that I was being too difficult and making unreasonable demands, then I guess he needs to find other customers willing to meet him farther on his side of the bridge. Those same customers won't be bothered by the context of these threads.
Thanks again for the support guys. I have a weight off of my shoulders right now, and can put this 3 day hell trip behind me, for the most part.
