For me the main issue is the cost. I have them on the 500 and miss them every time I drive my company car, but when I was ordering my car it was a £900 option and I just couldn't justify it for an extra that adds nothing to the value at resale time. If I was choosing the spec for a new 500 I would be tempted but in reality I wouldn't keep the car long enough to get my money's worth. Seems like a nice to have if you are buying used.
everyone i speak to says once you have them you miss them, in reality regret not ordering on current fleet, was tempted on the 500 but did have my resale hat on at the time
my gripe is only the halfrauds boys retrofitting without the auto leveling and washers, hopefully mot time will give them a shock
