Burning it seems a little extreme under the circumstances. Personally I would avoid the wanton destruction of such a vehicle.
Instead I would strip every useable part from the vehicle and ebay it... It is possible (though not likely) that having experienced a small dent to the bumper the doors will still fit. These are in great demand by those who have tried wading in their FLs.
While I appreciate that you may have serious doubts about the wisdom of said advice, getting as much back for the few remaining undamaged parts of your vehicle should constitute a priority which can then be realised financially and redeployed on a more sensible vehicle purchase.
