You can buy it back if you want. Take the new car and if the old car is cheap, grab that too! Sorry to hear though. I'm in Scarborough and we didn't get it nearly as bad as you folks closer to downtown.
Another guy said it before, and then I re-iterated it. Do not mess with a flood damaged car, IT WILL NEVER BE RIGHT.
