Well, if you need to sell it "asap", asking webuyanycar.com is going to get you a yes or no answer a lot faster than asking anyone here.
Unfortunately, once a vehicle has been branded with CAT D damage, your only remedy is going to be investing in a FULL mechanical inspection at an approved dealership or inspection facility with the hopes of an upward revision in classification or offering some kind of assurance that the vehicle would pass a structural and roadworthiness test as a condition of sale.
Best of luck. I hope this helps .
