You mentioned you are a new owner. A common problem among "newbies" (new owners) is that they take what the seller says about "minor" problems and optimistically believe any repairs would be inexpensive. They wind up overpaying for the car because of it's condition and get upset at the shop that tells them what they really bought and what it is going to take to fix it. I would guess that is part of your frustration. As pointed out in another post, and we assume they DID get in touch with you and asked for you authorization what would you have said? Can't put it back together and can't finish the work so now you are either going to "bite the bullet" and pay more or take it home in a trailer to sit. The shops that work exclusively on Deloreans don't have to inflate the job to make money, they have plenty of work so they are not looking to "get rich" on any one customer. They also have a reputation because it's a small world and word would travel fast. This problem that you face is not just a Delorean problem, it can happen at your local garage with your daily driver. The shop does it's best to estimate what a job will take but often it doesn't always work out that way. Not anyone's fault, things you didn't expect can happen. One reason many owners like to do as much of their own work as they can. You feel you have more control. Maybe you could try to do some work on the car yourself. This forum encourages it and offers everyone's advice and experience to coach you through. If it is any consolation many owners have spent lots more than you and wound up with less done. At least you know what was done was necessary and it was done by a shop that knows what they are doing and will stand behind their work. Enjoy the car and you will soon forget this minor problem.
