Yeah, they obviously want an opportunity to upsell you so they make you speak to a person to get the $35k model. It is a bad business practice from a consumer perspective, but if you have ever purchased a car from a dealer you know this type of upselling is unfortunately standard for the industry. At least Tesla won't try to sell you on rustproofing and tire warranties.

I'm curious, can you "upgrade" your car after the fact? Buy it and then later on call Tesla and pay for the software-controlled 'upgrade' you declined before? Is there any negative financial impact to it (are there fees attached or is it basically the difference you didn't pay prior)?
