Has anyone bought one, and if so, what's the experience been? My main concern is that the 2 cars I'm looking hardest at have both been serviced more than a dozen times in 2-3 years. and even subtracting the annual check ups and the 1 recall, that seems like too many times. I'm not looking for a high maintenance car, and Tesla tells me both that this car has few maintenance issues and costs, yet it's hand assembled, so more things can go wrong (and I guess have gone wrong). And what's up with the tires? I'm being told the tires need to be replaced every 5-6000 miles. Is that true? Seems nuts.
