I've got a 2003 saturn ion with 62k miles there was a factory defect with the engine and was replaced at 48k with an engine with 18k, and also has a new starter drive shaft, of course usual wear and tear on it, but nothing big I don't rag on it just cosmetic, everything works fine with it also has cruise control and a towing package... so please give a real quote just curious

You can get a ballpark figure from the websites Kelley Blue Book Official Kelley Blue Book New & Used Car Values - Kelley Blue Book and New Cars, Used Cars, Car Reviews and Pricing - Edmunds.com. The fact that you've replaced the engine is immaterial - assuming it runs as expected for a car of that age and mileage. My experience in using these sites is that the used car market values are typically a bit high.
