Our demo one arrived a couple of days ago at work & I was glad they decided not to send a white one. I think that might've looked a bit odd - the black does hide some of the proportions a bit, which is a positive in this instance.
The MPW badges on the door pillars were stuck on at different angles I noticed, which I thought was poor, but the regular 500L's seem well built so I'm sure the interior of the MPW will be just the same.
Saw the advert for it on TV last night too. I like the regular L more, but I'm sure it'll find a few fans because of undercutting several rivals on price & through its quirky looks, and once you look beyond that it seems Fiat have actually produced one of their most complete cars to date in terms of quality, driving, safety, equipment & practicality.
