Even though Elon Musk said earlier today that he's not sure how much of Tesla's Model 3 will be unveiled next month, you'll still be able to get in line right away. Musk (shown above posing in front of a Model S during its 2009 debut event) just tweeted that Model 3 reservations will be accepted at Tesla stores on March 31st, and online starting April 1st. You'll need to put $1,000 down towards the car's price, which will start at $35,000 before any incentives are applied.
