There's a few things here. If the repair shop hasn't disassembled the car any further than the photos you've supplied then they are likely assuming worst case scenario. Likely replacing radiator, ac condenser, intake and everything in front & around it. For me, the deciding factor would be whether or not your chassis rails have been bent, or if the damage is purely cosmetic. Based on the photos I don't think you'd be able to tell this without pulling the front apart, but if the rails are straight then it wouldn't be an overly difficult repair. Do you have the option of taking it to another shop to have them quote the work? I would expect it to be a reasonable request to have 2-3 shops quote if you were to ask. If nothing more, I'd be asking to see an itemised quote of what they're proposing to do before making any decusions. If the 7k worth of parts includes pieces that don't really need to be replaced then that's a different story. I don't think you should be angry at the repair shop, they are a business and need to make a profit to survive. Not only that, if they try to cut corners then they're going to be on the hook for future rectification work or issues that arise which no decent business would want. Sorry but I'm going to be the one to call it out and say this is completely unacceptable. You seem remorseful about your actions so I will give you credit for that, but it doesn't excuse them. If an inanimate object like a car is going to make you act this way then maybe it's time to site down and have a long, hard think about whether to try and fix it or just cut your losses and move on. Which would you rather have - the car, or your family? Because acting like this only lets you keep one. Is any car worth this much emotional distress? Either way, time to man the fuck up and do whatever is necessary to make it up to them.
