At the moment the C1 is our only useable car, and we're over 400 miles in now and I pretty impressed with it. Still in the running in period, but even keeping below 4krpm it's a nippy little bugger - you only really notice the lack of power when you're going up a slip road and are trying to get up to motorway speed. But above 4krpm the VVT kicks in which should help it a wee bit more oooomph when we start giving it some abuse.
It's not amazingly refined - but it was never going to be. Road noise is quite high and the engine is suprisingly growly considering it's puny size. Suspension is set up quite hard for a 'city car' IMHO, but that's not really a downside - we're used to much stiffer suspension. Seems to stick to the road quite well and is pretty well balanced I could upset it when trying to provoke it yesterday.
Stereo is pretty good, very glad we blagged the additional rear speakers and it sounds a lot better than the 107 demonstrator. Lots of little cubby holes inside, which are handy and it easily coped with 4 people in it. I love the rev counter, or the 'lollypop' as it's now nicked named. Managed to fit a big shop in the boot which we didn;t think we could manage, but the seats don't fold flat which isn't so good.
The first tank of fuel made it almost 400 miles which averages out at 49mpg. Was hoping for a bit more, but hopefully when the engine has loosened up it'll improve.
Only 2 problems for the dealer to sort out - a squeky seat and one of the rear doors needs adjusting as it doesn't quite sit flush. But overall we're very happy. next time I drive it it'll be well over 500 miles so gonna give it some welly to see how it performs 'on cam'.
