>>10938310$/kg to Mars surface is much higher than to LEO.
To bring something to LEO, you fuel Starship and Super Heavy with methalox at super cheap Earth prices and launch them once, occupying them for a day.
To bring something to Mars you have ~8 launches of SS/SH just to have a SS fully fueled in LEO, then SS goes to Mars, is fueled with methalox at super expensive Mars prices, goes back. SH is launched 8 times and used for 8 days. There are 9 SS launches and one SS was away for at best a year and more likely almost 4 years (9+26+9 months), meaning much higher SS depreciation cost. If they achieved $1,000/kg to Mars surface that means they would have achieved $50/kg to LEO.
Even if its $1,000/kg that still means you can spend $80,000 to save 100 kg and its a profit. That means more titanium and carbon and less cheaper steel variants found in a COTS car.
