Faults:

Nothing so far and knock on wood. The motor mounts are starting to feel a bit saggy, will have to upgrade to the latest design eventually. After 20K miles the tires have about 40% thread left.

General Comments:

Love the design, the materials (real wood, wool, leather, carbon fiber everywhere), the handling, the comfort, the performance, perfect for commuting (might not be the best to drive across the country, but it could do it if needed), and with the REX option you can just keep driving and driving if needed.

I jailbroke the REX to be used at any time after 75% battery capacity and expanded the gas fuel level sensor capacity to get around the US model specs. Battery upgrades or full/partial replacements are available at reasonable prices. Was daily driving my Jeep TJ, but the trip to the gas station got old, found my i3 with low miles and a 90% depreciated price tag at a dealer which game me a decent deal, and after driving it all this time and the government tax credit I have avoided to purchase ~1400 gallons of gas, this car pays for itself. It takes around 17 KWh to charge the battery at $0.07 per KWh for a total of $1.19 to charge at home and free at work around town.
