Covid is slowing down most all commerce. Prices of used cars, gasoline, diesel, etc are all under pressure.
With so many governments issuing new regulations for gas/diesel vehicles, and so many people wanting to step up to cleaner and more powerful electric cars, the prices of most ICE cars are going to be under pressure as well.
Many city inner circles are either banning ICE vehicles or charging them to enter the downtowns. ICE owners need to leave their cars at one of the outter ring roads and take busses/trains into the city centers. Some governments have already given notice that in the near future they will ban the production of gassers all together.
On a happier note, many of those governments are instituting rebates and tax credits for buyers of certain EVs.
As an example, when I purchased my X in California I was given a Federal Tax Credit, A State rebate, a Utility rebate and a 30% credit for installing my garage charging system. Also it was eligible for a 100% write off for my business with accelerated depreciation schedules.
The World is changing, and it is predicted that EVs will become more in demand and valuable and gassers will depreciate much faster as the pressures increase.
Right now, the lower prices of Gas/Diesel are making buying a new gasser appealing, but when the prices go back up again those gassers prices will drop like a rock.
In the US, people are still buying giant travel RVs that get only 8MPG. When gas prices ramp back up they will dump those as well
