I would check Edmunds for a True Value figure, then go to Ebay and do a search of completed auctions for the car. This will give you some idea. You also need to pull a Car Fax report and see if the Bambi repair was reported by the body shop or insurance, if it was this will result in a neg. towards the resale. If you don't have access to a free complete report send me your VIN and I will run it for you.
Another thought would be to take it to CarMax and get an appraisal.
