In the Q1 2018 $TSLA Quarterly letter, Tesla claimed that it had Model 3 "net reservations" that "continued to exceed 450,000 at the end of Q1."
As of the end of Sep 2019, Tesla has delivered a total of 356,084 Model 3s.
This implies that no more than 200,000 (and likely less than 150,000) of the Model 3 order backlog actually ended up purchasing a car.
At the unveiling event, Musk announced Tesla had 135k orders for the Model 3.
On 4/1/2016 Musk tweeted that Tesla had 180k orders for the Model 3 and then later tweeted that Tesla had 198k orders.

In reality, the company ended up producing 152,977 Model 3s in 2018.
In the Prospectus for that offering, Tesla wrote " we held deposits from about 373,000 customers who had made reservations for this car."
Tesla also sold 6.5MM shares in the offering as well.
The last time Musk was desperately pumping reservation numbers, his financial empire was on the verge of collapse.
