Hi.
I'm also fairly new myself, having joined a couple of weeks or so ago, again a 2014 500L 7 seater owner, 1.3 diesel. We've also had a couple of Fiats previously,- I'm quite liking the spaciousness of the car and how relatively high off the ground it is to get in and out of, a necessary consideration when you're not so young anymore! Davietich, unfortunate that you're having problems, although personally, I'm not a fan of the 'stop/start',- mine is switched off, and will stay that way as I'm unconvinced that it will make any useful contribution to my mpg and in the longer term won't help the life of battery, alternator or starter motor. As my car is the 'Popstar' version, I don't have foglights (may fit them later) and although I don't need 7 seats normally, they'll come in handy when we have the Grandkids on board. I'd sum up the car as being comfortable, spacious and hopefully reliable and economical in the longer term.
Cheers,
Keith.
