Hi, We are all in this position, so we all have the direct choice of accepting things as unfortunate as they maybe or decide to opt out of the scheme, the choice is specifically personal.
The economics of the situation is something that should have been thought about prior to entering the contract not after, like all contracts the supplier of the goods are not responsible for losses incurred due to unforeseen circumstances.
So we either accept the world wide economic situation or send car back and cut our losses if it is possible.
I personally choose to keep the car as I need it , just my opinion , wish all all the best in this unfortunate situation, Cheers Michael
