Advice please our 2019 Sorrento has 43,000 miles on it our favorite Service Advisor and our favorite Salesman says we should trade it in before it hits 50,000 miles. Do you guys out there agree that's good advice or should we keep it and hope we don't have problems after 50,000 miles that we will have to pay for. We are Senior Citizens I'm a Retired Respiratory Therapist on fixed incomes and struggling financially. Kia says our car is worth more pre 50,000 miles and they can sell it as Certified used car. Any advice is welcomed. I checked what it's worth in Kelley Blue book but don't know if they will offer us trade in value $19,158-$21,167. Our car looks mint clean back seats have never been sat in and no kidding our car looks exceptionally fine and is red in color. Please advise what I should do, Thanks! PS Any advice on if we should expect to pay near or under MSRP? What is a good deal on a new plain model EX like ours is currently.
