Be careful if you purchase car from this guy
I detailed this tesla so he could sell it. He tried to get out of paying me, not returning any of my calls. So be careful if you purchase it from him. Get everything in writing and dont take or believe any verbal promises from him. By the way the car turned out awesome and when I asked him what was wrong with the detail he could not give me any reasons. I have run across guys like him in the past and they say there is something wrong with the detail to get out of paying. Gives you a glimpse of what kind of guy he is.

From my understanding it really depends on how hard the batteries were driven and the overall state of charge (SOC) of the battery.
For example, if the owner did mostly "range mode" charges and charged the battery up to 100% and drained it down to 2%, the batteries won't have the same lifespan as someone who uses a "standard mode" charge and keeps the batteries between 20%-85%. Secondly if performance mode was used and fast discharging of the batteries occurred for the majority of the time, that too would have an impact as compared to someone who drives the car like a daily commuter and not like a race car.
The real evidence will be in the car's logs.
Also the SOC is a sign as well, meaning that you won't get 190 to 195 ideal miles in a standard mode nor your 240 - 245 miles in range mode if the batteries have degraded.
Does anyone have a link to the 200k mile Tesla? I'm curious what his charging pattern was and if he had the original battery as well as what his current SOCs are.

If you figure the stated 20 percent loss of range for 100,000 miles that means owners who are at 50,000 miles should be a 10 percent down in range. (if linear) I'm at 44,000 but can't tell my losses accurately since the various firmware changes have dropped my range so much I don't know where I am in relation to when I bought new.
As i remember when new, I would get 192 miles showing in Standard and 238 in Range, Now it's about 182 S (on a good day) and 228 R. Again many firmware changes dropped my range when I charged the day after getting the car back.
Probably not much use to you. I guess I just wanted to vent.

Eric, what firmware versions and what changes did you make if any when you began to see your range being adversely affected? I'd like to compare with mine and see.
My roadster was produced in April 2009, has 4200 miles and I get 190 on a standard charge. When its done charging it will then settle down to 188-189.
The last firmware was updated by Tesla in Jan 2012.
Here's the history of my firmware updates:
timestamp, firmware version
04/15/2009 18:03:25, 3.2.16 12
06/11/2009 09:59:50, 3.3.1 12
10/07/2010 15:59:30, 3.5.18 12
01/26/2012 11:39:54, 3.6.7 12
Also have you been saving off your logs since you owned your car? If so you should be able to use excel or a plotting program against time SOC over time and mark the dates you're firmware was flashed. You then could correlate the updates to the drop in SOC.
Lastly when have you last balanced your pack? This I read can occur when the roadster is in storage mode. I believe you need to charge it full up to standard mode and let it sit for some time (this cycle has to be repeated 2 to 3 times). I don't know if you need to pull the pack down to any specific range though.

The car is older than any of the user generated readers so I was not keeping logs. Not really a logger type person. Talk to Tom Saxton and a few others here. The only changes I made when presented with less mile was to drive shorter distances.
