I got exactly what I wanted.
The thing is that different people will want different stuff.
You have to decide for yourself how much you care about getting the sunroof, for instance. My fiancee is photosensitive and doesn't like sunroofs.
You have to decide whether you prefer leather or textile.
You have to decide how much you care about fancy paint.
You have to decide whether you prefer showy giant rims which will get wrecked regularly and need frequent replacement (21"), or wheels with some sidewall which can actually handle bad roads (19"). You can tell which I prefer.
You have to decide whether you are taking this car on the track (Performance / Performance Plus) or whether you are driving it on the road at legal speeds. As far as I'm concerned, Performance is pointless unless you're taking the car on the track or have money to burn. I have a non-Performance and I am leaving other cars in the dust, routinely.
The battery size you get depends entirely on what sort of driving you plan to do, and the available chargers in your area, and how much money you have. If you can't be bothered to plot out your possible trips with reference to potential charging points, get the larger battery.
The stereo system depends on how much you care about such things. I'm happy with the standard system. Audiophiles will want to install custom systems. If you're somewhere in between, then I guess you will want the premium stereo. It's worth noting that the standard stereo system sounds FAR better than the systems in most cars *simply because there is no engine noise*. Test-drive a car with the standard stereo before you consider getting the premium.
I'd also get Supercharger access, definitely. You'll be ticked off if suddenly Superchargers show up and you WOULD have used them...
The twin chargers... well, there are an awful lot of 70 amp charging stations popping up, so I'd get that, definitely, for the same reason as the Supercharger access.
If you have two drivers, or a garage, I'd definitely get the tech package, even though it's pricey. I've used every feature of it, I think.
I didn't get paint armor based on (a) other people's reviews and (b) my car is white, and people didn't think it looked good on white. If my paint is damaged, I guess I get it patched.
Practically nobody should bother with the HPWC. The NEMA 14-50 will charge from 0-full overnight. In order to exceed its limits, you'd have to drive further than the car's range during one day, *and be home in the middle of that*, which means the HPWC only seems useful for people with "travelling salesman" driving patterns.
