Who cares about the number of owners? It could be 14 very very good ones or 1 absolute ***hole. Judge the car on service history and condition?
My car has '3' previous owners including me because the DVLA ****ed up. They put the car in my name with the postcode attached to my surname (?!?!), right address. I sent it back annotated to the hilt saying 'it's still me, DON'T add another keeper!' And what did they do? Add another keeper. So I am the previous and current owner....Before that, the original owner had done 900 miles in 12 months....
PS lovely looking car, only thing I would say is maybe split the 'standard spec' features from the 'options' - a lot of buyers like to see it as presented on the AUC, i.e. with the extra kit listed separately so you can see how many toys it has over stock?
