Tesla Model S
We estimate that Tesla Motors sold ~17,650 Model S sedans in 2013.
That figure puts the Tesla Model S atop this chart of luxury vehicles in terms of 2013 US sales:
Puts The Model S 2013 Sales Figure More Accurately at 17,650
Yes, we're well aware of the flawed 19,400 Model S sales figure. We didn't compile this list though and, be it 19,400 or 17,650, the Model S still is #1 on this chart.
Finally, we'll point out that the inclusion of the Cadillac ELR is suspect, seeing that it was only offered for sale to the public for the least few weeks of 2013.
Hat tip to Bill Jones!!!
