That really depends on the nature and extent of the failure. A reman is gonna be waaay faster and easier to do yourself, plus if you intend to stay with it, there is the warranty. Most remanufactured engines come with a pretty good one. That is also worth a few bucks for resale, as long as it can be transferred. Build it yourself and you get zero warranty, but more control of the parts used. As a tradein, it won't matter either way, and as long as it's running as it should, keep your yap shut. Don't you guys have dealers that scream, "PUSH IT,PULL IT, BLOW IT UP IN YOUR YARD,HAVE IT LAND IN OURS....7000DOLLARS FOR ANY TRADE!!!" I always wanted to roll in with one the complete wrecks in our yard, on the roll back, and start the games. Push the VX in, dressed as Berber nomads. Better still... pull it in with a donkey. Wear your best Jesus clothes. The possibilities for shenanagans are endless. Go reman. Good luck. Wayne
