I don't think it would be wise to do a trade-in of such a new vehicle. You will be taking the first 2 full years of depreciation and the value loss caused by the crash.
Any accident plays a huge role in the trade-in appraisal. If it has a bad CarFax it makes it very hard for us to re-sell it. So we have to ball-park what we can expect at auction and hope that we are spot on with our appraisal.
