Just closing the loop on my experience. We did upgrade to the MCU2 last week after a few weeks with the MCU1. Our cost was just over $2,400 with tax ($2,250 before tax). To confirm again (as others in this thread had already), this upgrade does include the latest FSD computer, so no need to request that as a separate service request.
In my week-plus of experience, I believe we're going to be far happier for far longer with the MCU2 upgrade than we would have with the MCU1. In my opinion, it puts our 2017 on par with the current models. While I spent more than the cost of a good MacBook Pro to buy what is, essentially, a couple of computers, Tesla did build a ruggedized system that's designed to operate more like an appliance. I can appreciate the difference, and I feel like it upgraded not just the components but the entire experience (driving, parking, traveling, etc.).
Putting aside the additional Infotainment features, the interface at the dash and on the touchscreen is far more capable with respect to the tracking of the road, traffic, signs and signals, etc. While the horizontal screens in the current models show a wider area on the traffic around the vehicle, the core data around the immediate area surrounding the vehicle (showing in my dash directly in front of my line of sight) is much more desirable. Obviously, this is the same on the Model X and the Model S, and a big reason why I chose to purchase the Model X over the Model Y (although there are aftermarket mods to give you a similar dash experience on the Y and 3).
As I do have Enhanced Autopilot, this system seems far more responsive as well. Not that you really noticed the delays in the ride experience if you didn't have the upgrade, but, comparatively, the current system is a little more on the ball. I'd have a hard time going back. Ultimately, that improved responsiveness means additional safety in addition to a better experience.
I think someone said it earlier: the upgrade improves the entire car. While it's not quite replacing the "brain" of the vehicle, it's pretty close. This upgrade path is another way Tesla differentiates itself in the marketplace. There's no way I could do anything close to this with a Toyota, Ford, or other traditional manufacturer, and I've yet to see another EV maker offer similar (although I'm really not looking).
After taking our first plunge into Tesla with our used Model X, I wouldn't have a problem taking the used path again if we get more car for the dollar. If you just factor in the MCU2 upgrade to your purchase decision, you won't go wrong.
