Personally, I don't think Tesla should be giving refunds. They set a bad precedent IMO. Although admittedly traditional auto manufacturers don't have such frequent and rollercoaster price changes like Tesla does - it's a myth to believe that purchasers of traditional autos pay "the same price" for their cars. Although there is an MSRP, that's just that...a suggestion by the manufacturer to the dealer. The dealer can actually drop the price by a good amount (although that cuts into their profits obviously) - or they can raise the prices for in-demand models
Some may call this market forces. Others call it price gouging. But the result is the same: 10 people buying the same exact car at 10 different random dealers will likely have a bit of a spread between highest $ and lowest $.
Is GM or Toyota going to issue a refund to the people that paid more? Will the dealer?
But a compromise for allowing a one time downgrade in the first 7 days (or for those who have ordered but not yet taken delivery of their SR+) seems reasonable.
I would like Tesla to get out of the habit of giving refunds though - the only exception being if people don't get what they were promised (I'm looking at you, "FSD" sold almost 3 years ago with timelines for activation that were 0% accurate).
I would also like to see Tesla not be so jerky (either up or down) with their pricing changes though. I know they are iterative and don't do model years in the same way as old school manufacturers do, but perhaps they could at least get into consistency with giving a certain amount of notice for their changes. I'd argue for at least 1 month, like:
"Model 3 Standard Range Plus, Dual Motor and Performance will have basic AutoPilot functionality included starting May 15. Base price of these cars will increase by $2000 (AutoPilot as an option was $3K) which will result in a net $1K savings for most buyers since AutoPilot is an extremely popular option. However, if you do want a Model 3 without AutoPilot, order in the next 30 days."
With that kind of warning (and the same for taking base SR off-menu) I think there would not be nearly as much anxiety and angst (although there will always be some!)
