1/ Do you use your car as a daily driver?
Yes, but I work from home. We took delivery on June 5, 2009 and have 29,628 miles on the odometer. Now that we have a Leaf, the Roadster gets less use in the winter.
2/ What is your driving style: aggressive, or as an everyday commuter car, etc
It's a mix. Sometimes I'm 80 mph crossing the I-90 bridge, sometimes I'm in the right lane doing 60 mph. Most of the time I spend driving the Roadster, I'm having way too much fun.
3/ What is the range you usually get from a full battery charge?
235 ideal miles in range mode, 183 in standard. We got a new battery pack in November, 2010, about 15,000 miles on it now.
4/ how long does it take to charge your battery?
Typically an hour or two at 240V/32A, but as others have noted it takes 30 seconds to plug in and the rest happens while I'm sleeping. It beats the hell out of going to gas stations.
5/ has your battery performance/range changed over time?

6/ how often does the car break down or require service?
It has never broken down and required service. The subwoofer amp had a transistor burn up, which was a little scary until they figured it out, but the car was working just fine. At the one-year service, three battery sheets "failed the bleed test" whatever that means. I was cleared to drive it 180 miles to Portland and take it drag racing, where I set a new personal best 1/4-mile time, 12.978 seconds ET at 103 mph. To make a long story short, Tesla replaced the entire battery pack at my convenience in November.
7/ how much money do you spend a year on maintainance and servicing of the car
$600/year, plus about another $600 replacing rear tires every 12,000 miles. My previous car was a 1995 Acura NSX-T, which also chewed through rear tires at about that rate. There are some owners experimenting with a different set of tires that may allow us to use cheaper tires that last have a 40,000-mile warranty and don't degrade performance.
8/ how much does charging the car add to your electricity bill?
It's completely undetectable, a very small expense compared to burning gas. We have driven the Roadster 28,257 miles since having our HPC installed with a dedicated meter. Since having our HPC installed with a dedicated meter, we've drive 28,257 miles on 7,106.2 kWh. At our electric rate, that's about
$782. To drive the NSX that same distance would require 1411 gallons of gas (21 mpg), which would cost $5,643 at $4/gallon.
9/ what are common problems that you have experienced with the roadster
The center console backlight didn't work. It took two replacements to get that fixed. The fogging headlight problem has improved, but still happens occasionally. There have been a few other minor issues over the past three years, but they've been minor enough I can't even think of any more than I've already mentioned.
10/ if you had to do it all over again, would you still get the Roadster?
Purchasing the Roadster was a political statement for us. We wanted to support the only company even talking about making an electric car in 2006. Now I'm not sure I'd spend so much money on an exotic sports car. However, I can't imagine ever parting with it. The Roadster offers by far the best driving experience available at any price.
Six weeks after getting the Roadster in 2009, I sold the NSX-T, which I thought I would keep forever. It had 24,000 miles on the odometer. In less than three years, I put more miles on the Roadster than I did in 14 years of driving the NSX because it's so much more fun to drive the Roadster.
If I had to start with an empty garage, my first purchase would be a Nissan Leaf. Then I'd wait as long as possible to decide what the second EV would be.
