I don't understand the appeal of the HPC except to have a nice looking station. In that case, you can run it on a 50 amp breaker (or 70 amp like I suggested above) and be fine.
Maybe we should do a poll about Model S owners putting in HPCs. I would have thought the percentages for that to be really low, like under 5%. Your post, however, makes it seem that every middle American Tesla is sold with an HPC. Why do you think that?
I suppose the alternative would be to buy and extra cable, one to keep in the garage and one to keep in the trunk.
I think I'll just feel out the other estimates I've asked for and see how I'm feeling after that. What you guys are saying makes a lot of sense.

I just detach the UMC when I travel. When I'm in town (especially since you'll have the 85 kWh pack), you'd never need the UMC so it's safe to leave that at home. The HPC does look better though. Good luck.
I'd think the main reason for getting the HPC is so that you could charge other Teslas.
Sufficiently advanced magic is indistinguishable from a rigged demonstration.

BTW, +1 on Stider's Tell them it's for RV's, not EV's suggestion. Just say you want a 100 amp subpanel with a single NEMA 14-50 for RVs for now. The subpanel is always a good idea for expansion (Air conditioning, power tools, etc.).
I just had a 50 Amp breaker and a 14-50 receptacle installed this morning. Lucky for me, the breaker box is on the driver side of the garage, so I had the 14-50 installed about 6 inches below the box. Still will cost me $300 bucks (service, equipment, & permit).
I've got a 70AMP HPC on my wall (primary reason being that I like the look of the HPC, rather than an ugly box hanging off a plug on the wall), but run it at 48Amp.
Last night, I came back after a busy day with @60% SOC. Plugged in, and a little over two hours later charging was done at 96% SOC. The car (and charger) that sat idle for the rest of the night (about 10 hours before I needed it again).
If I could get a 40Amp HPC, I would. (yes, I know you can in USA, but at the time here in HK they were only selling the 70Amp versions, and they can't be dialed down by that little rotary dial - which doesn't exist on the HPCs here).
Curious what mine will cost, it should be dirt cheap. I've got a dryer breaker I'm not using (switched to a gas dryer) and my breaker panel is about 3 feet from where I'd want the plug, so it should be inexpensive.
