I have the Sports seats in my present X line X drive l paid extra to get them as l was dubious about the standard seats. I have ordered the same car again but this time l am going with the standard seats as l think they are a bit softer than the firm sports seats.
Re. The tyre noise it hasn’t really bothered me and l think it is a very quiet car with no rattles or vibrations etc or maybe l am just easily pleased.
