The refund clause matters more than the deposit size: Lotus's £250,000 was refundable, Aspark's reported $1.15 million was not, and De Tomaso's ~35% milestones are non-refundable.
Tesla Roadster Deposit Refund and Hypercar Waits 2026
Tesla took $50,000 Roadster deposits in 2017 for a car promised in 2020; nine years later no customer has one, Musk now says 2028, and Tesla has reopened reservations at the same $50,000.

02Worth knowing
What the AIs noticed while building the list.
Tesla's written terms and its practice differ: the agreement promises a full refund, but there is no cancel button, and Sam Altman's refund reportedly went through only after he complained publicly.
Not every wait loses: McLaren's Speedtail took reservations in 2018 and delivered in February 2020, essentially on schedule.
03Questions people ask
Did Tesla refund Roadster deposits?
Yes, in documented cases, but slowly. Marques Brownlee got his $45,000 first and the $5,000 about a week later after days of calls, and Electrek corrected its report that Tesla kept the $5,000.
Source ↗Is the Tesla Roadster deposit refundable?
Yes. Tesla's terms allow a full refund of the $50,000 reservation until a Motor Vehicle Purchase Agreement is signed, though you have to contact Tesla directly because there is no cancel button.
Is the Tesla $250 deposit refundable?
Generally no. The $250 order fee on regular Tesla models is treated as non-refundable under the order agreement. It should not be confused with the $250,000 Roadster Founders Series or Thrust payment.
Source ↗Will Tesla refund a deposit?
For the Roadster, the contract says yes before a purchase agreement is signed. Sam Altman's $50,000 was reportedly refunded within 24 hours, but only after his complaint went public.

6How the places were set
The same entry written differently by different AIs was counted as one. The more AIs put an entry on their list, and the higher they put it, the higher its place. "AI agreement" shows how many of the AIs had it on their own list. Sources are only those the AIs found themselves; nothing was added by hand.

What ChatGPT noticed
The Aspark Owl's reported reservation amount changed sharply: $1.15 million in 2018 versus a reduced €50,000 offer in 2020, so a single 'Owl deposit' figure hides different cohorts.
Lotus's refundable £250,000 Evija deposit and Hennessey's $300,000 Roadster order letter illustrate why refund rights need to be read separately from deposit size.

What MiMo noticed
The Roadster's range promise quietly halved. Tesla quoted 620 miles in 2017; the Oct 15, 2026 reveal lists 300 miles for every trim. Meanwhile the claimed 0–60 dropped from 1.9 s to 0.81 s with thrusters — the goalposts moved in opposite directions.
The Roadster is not alone: the Koenigsegg Gemera waited six years (2020→2026) and lost its promised 3-cylinder engine along the way. Hypercar reservation holders routinely fund development and then get a different car than the one they reserved.

What Kimi noticed
The counterexample: McLaren Speedtail took reservations in 2018 at £1.75M and delivered in February 2020, essentially on schedule — proof that hypercar deposits can work when the program is funded and finished before it's sold.
Waiting can pay in-kind: Gordon Murray T.50 depositors waited ~3 years, but cars that cost £2.36M now trade around $8M — the reservation itself became the investment.
