Thanks to a successful referral, got a code for a Founder Series (Radio Flyer) Model S for Kids whose list price is $499: Tesla Model S for Kids. Can't use it anymore given that my son's about to turn 11. If anyone's interested, I can take payment via PayPal and send the redemption code to you by email or private message. You can customize and order it directly from Radio Flyer. Current status says that new orders for the car will ship in October. Asking for $380. Thanks for your interest!
