I've come from a mini so I'm used to a stiff suspension set up but go kart handling, the sport suspension on the A1 feels like driving on pillows compared to the mini, but I can't say the handling is exactly impressive.
I know they aren't built to be fantastic handling cars, but I have noticed it struggling to hold to the road when I try and get it round sharper bends.
Had an A1 race back from Castle Combe to the M4 the other day across the country roads and it was pretty good along there, but there weren't any particularly sharp bends.
It's still fun to drive, I just wish I could throw it round some sharper corners!

I test drive a DS3 and the handling on that was shocking, couldn't get round a roundabout at a reasonable speed without it feeling like it was going to come off the road!
