I don't take anything personal, it might appear so, but you can't hear my voice through my text responses: I am not angry, nor upset, I just don't understand such attitude, that's all. I've never hated that car even though I had plenty of reasons to hate it, but it just wasn't worth getting mad over it more than the inconvenience when it happened, and once the time came I happily moved on, and I still remember that car with fond memories.
A loss is a always a loss, regardless of new/old/used, the cost relative to resale value was a 1/2 of total price loss, it was a big loss. But money, however, can always be recouped, one can always work harder to make more money like you said. I personally value time and sanity over money any day of the week, so if taking a loss saves me time, and my sanity, then so be it. It sucks, I get it, trust me, I know full well how much it $uck$ (sucks). When facing a situation like that, in my experience it has always paid to keep on a positive attitude, no matter how ugly or unfavorable it might seem.
As for Lipster and your situation, at the point of needing a new engine (Lipster), or the UConnect critically failing, or the doors not opening correctly (you), or anything critical like that in terms of functionality, etc, I would simply start looking into a lemon law, especially if still under warranty. Perhaps contacting a lawyer might be a better use of your time than having your new vehicle sitting in the shop depreciating at your own expense. Like I've already stated, that is time you are not enjoying the vehicle you paid for, and time can never be replaced.
We certainly buy cars based on different parameters. If you start from the premise that you truly like the car, then one can always work the rest of the problems out. Buying a car IMO, is a similar experience to asking a girl out, in order to ask the girl out you (usually) have to like the girl first. You don't just go ask a girl you don't like out on a date, then ask a list of requirements and if the girl checks all out then you keep on dating. Those kind of arrangements usually don't end well...
