Car has shown no wear on leather seats or elsewhere. No squeeks. No issues. My Lexus LS430 had more problems at this mileage and mention this because at 1/2 the price makes Kia Optima a compelling used car buy.
On smooth roads cruising is solid and quiet. When roads get rough noise et cetera become an issue. Gas mileage is fine (31-34 mpg) up to 65 mph but drops below 30 mpg at around 70-75.
