If they’ve already bought the car Elon already has their money. Buying another car because we now know what a piece of shit Elon is, doesn’t change that.

Their process is more complicated.

For congress to remove Trump first the house needs to vote with a 50% majority to impeach Trump for “Treason, bribery, or high crimes” the house does get to decide if something Trump has done meets that bar.

Then the senate needs to decide to have a trial not a criminal or civil trial, but a trial to decide of Trump should be removed from office.

Then the house gets to present its case proving the crime, then if the senate votes with a 2/3rds majority to convict, Trump would e removed from office, and barred from any future government office. If convicted, VP Vance would become the president until the next election.

Impeachment is a remedial process, not a punitive one, it can only remove Trump from office it can’t punish him for his crimes, though he may face a separate criminal trial for the same crime at that point.
