I had 2 500's, a 1.2 and a twinair. The adam is a far better car. The 500 to me, never felt composed, bounced all over the place and banged and crashed over potholes or battered Tarmac. It is a cute car tho but I feel it's more style over substance. I also think its way overpriced. I love the adam, I've got the 1.2 and am more than happy with it. It's still fairly new, not even done 1000 miles yet so it's still a but tight but it is nippy, and holds its own on the motorway. One thing I like about the engine is that it can cruise quite happily at 30mph in 5th and pick up pretty well when you need to speed up without changing down gear.
