BMW 535i Twin Turbo Fast Nice Ride

I hate to sell my nice bmw but it’s time for someone else to own it . Has 182000 miles highway nice taken care of ride . Brand new water pump from the bmw dealership spark plugs battery oil change . Just passed inspection . Check engine light does come on and it goes away on its own . Shows catalytic converter . I have been driving the car with the mat light for 4 years it has never gave me a problem . Still passes inspection doesn’t affect the car from driving perfect or anything . Looking for 5600 for the vehicle . Have done alot of maintenance on it . No low balling . Thank you will try to sell for a week or so if no one wants it . I’m going to register it and keep driving . Thanks for looking
