Kia Optima 2018 Estate 1.7 Diesel

Hi I am selling my Kia Optima Estate this car drives perfectly and has never given me an ounce of trouble apart from changing a few bulbs! This car is a really clean big car and the backseat passengers have lots of leg room and the boot is huge! With the backseats down the space is incredible. There's 4 new tyres gone on it before Christmas when it was last serviced. It has always been serviced regularly and always looked after. The nct is up next month but I have it booked to be done this weekend so that it will be sold with a fresh nct also. Tax is up in June. The only thing and it was like this when I bought the car is that the alloys have a kind of discolouration to them Kia wouldn't stand over these with the warranty remaining when I bought it. That is a cosmetic issue but not mechanical other than any inspection is welcome.
