Well, one thing I will mention is that the robots can be off. LOL. For example with my car, there was a paint imperfection in the back. I guess the robot didn’t spray one back panel enough and the paint is thin. Also, my hood had some rock chips. I complained and Tesla is painting those areas over again. They gave me a loaner car to use until it’s fixed. Also, a P85.

Still LOVING the car. I can safely say I will NEVER buy another ICE car again. I’ll get the Model X once it comes out as well.

Also, regarding the meter I posted on the Tesla forum but I’ll repost here:

I have the dedicated meter from SDGE so the nice thing is you can experiment with this sort of thing. Since our meters started out from 0.00 it’s easy to track. Just for kicks, I’ve been noting exactly how many miles I charge each night then log it on a spreadsheet in the morning at what the kWh shows on the meter. I’ll keep some meaningful period of at least a month then I’ll post a Google Doc with the spreadsheet for anyone interested.

I would have thought that the green led light on the HPWC would at least draw some electricity but I’ve never noticed the meter have changed at all from the last reading. So it must not be anything noticeable at all which is great.

For example. 3 random samples of charging below. (For frame of reference I have a HPWC and dual chargers at 80 Amps and I set to charge at 1:30 AM).

168 rated miles. It used 66 kWh. I have TOU EV super off peak charging rates with SDGE in San Diego

https://www.sdge.com/sites/default/files/regulatory/schedule_ev-tou_090113.pdf) which comes out to about $10.56 to charge the 168 miles.

155 rated miles used 49 kWh for an effective price of $7.84

142 rated miles used 45 kWh for an effective cost of $7.20.

Also, for further reference, on Tesla’s website — http://www.teslamotors.com/charging it showed 170 miles as only using about 55.9 kWh with the HPWC and dual chargers. And explained by other Model S owners, you will use more energy for the car and the cable while charging so it will always be higher than what Tesla’s website shows.

Estimates above aren’t exact and just estimates. I’ll need to see what SDGE charges with taxes and usage fees and possible generation fees. I didn’t get my bill yet since I got the dedicated EV meter so I’ll see how it affects the rates.

Hope this helps.
