INCORRECT/FALSE BUYING CRITERIA

I wanted to sell a car to them but apparently the car does not meet there criteria. I read through their criteria and I would not have wanted to sell if I thought it did not meet the criteria. The car is clean, about 13 years old which is meeting their criteria, mileage is less than 100 000km, I'm based in WC and service history is suffice so I struggle to understand why they said I could it does not meet "their critera". This is not the first time this is happening, this actually makes me upset and make me not want to even purchase a car from them and recommend them! I'm sorry but I won't deal with them. I understand you have a reputation to live up to but then please change yo buying criteria to avoid this!!!!!!!
