 Great handling but there it ends. One of the most unreliable cars I've owned (and I've had Italian cars!). Some of the problems the dealer has been unable to fix because they are fundamentally flawed: radio (because of terrible computer in the car), transmission shifts. If you need to find it, look in the shop.
