I kick myself daily for not getting the twin chargers. Yes, I know I can get them retrofitted, but at a very severe premium. I have had occasion to use the Roadster charger in several Tesla stores, and it would be REALLY nice to charge at 70 amps. When you've got your wife roaming around in a Mall it gets expensive the longer you have to stay!:wink:
I'm glad I
did get the twin chargers and glad that I
cancelled the HPWC.
The twin chargers are mainly useful for when you visit places with greater than 40 amp charging (such as Tesla stores) and while those aren't everywhere, if you visit or are near one, you'll be thankful from the first day that you're able to suck in a few more electrons while you visit that destination. As other have alluded to, its not worth it to retrofit due to the expense but with the original configuration, it's not too expensive.
The NEMA 14-50 outlet while charging at home is more than enough. In fact, I usually turned down the amps to 5 or 10 amps so that it will not charge too fast and finish way before the car is needed the next day. So instead of getting HPWC, use the extra money and install NEMA 14-50 outlets at your most common destinations -- parents, in-laws, etc.
If you're new to EV cars, what I've learned is that waiting for the car to charge at home is very easy because you have so much that can occupy you and help you pass the time (like sleep). However, killing time somewhere else outside your home while waiting for your car to charge goes by very slow, with the possible exception of the Superchargers.
Regarding the 3rd row and tech package. One thing I didn't know when we originally ordered them, is that there is a button on the inside of the trunk for the kids to open and close the liftgate by themselves. Our kids are a little older and they are able to get in and out on their own without much help from us.
Regarding P85 versus standard 85. Be honest with yourself. If you're the kind of person that always went for that bigger motor and
actually used it, and the P85 is within reach, then you have your answer.
