My engine seized due to lack of oil - although I did have an oil change less than 2 months ago. I am wondering your opinions and advice on selling the Jeep as is, or replacing the engine with a used engine instead. The quote I received from the auto shop for a new engine replacement is $4700 (parts/labor/tax incl.). What would be a fair engine replacement price? What do you think the resale value would be if I were to not replace the engine, but to sell it as is? Would you trust a used engine replacement? She is a '99 2.5L 4cylinder manual. 90k miles only. Looking for insight on the best options, not adverse to selling her. Thanks!
