In the last 4 quarters Tesla has delivered 271,521 model 3s. That would make it about the 12th best selling car in america. That is about as many escapes ford has sold. That is pretty phenomenal.
That's Tesla's total sales worldwide. About 50k of those sales are Model S/X. Their total sales for Model 3 in the US are at 114,500 for the year. Source: https://insideevs.com/news/373812/ev-sales-scorecard-septemb...

Edit: Just realized the Model 3 actually is the 12th best selling vehicle in the US for September! 20th best selling vehicle in the US in Q3 :) Source: http://www.goodcarbadcar.net/us-vehicle-sales-figures-by-mod...
