I have just bought a 2005 petrol note. I own a Hyundai Tuscon and a Mitsubishi Mirage, the Note is MILES lighter on the steering than these cars. In fact I would say it has the lightest steering of most cars I've ever driven. Love it!
I'm chipping in to say that I think the note has much heavier steering at speed than I'm used to. It's fine at low speed.
Our other cars have hydraulic power steering, with none of this fancy reduction in assistance as you go faster like the note has.
I guess mnl that I got used to the speed sensitive steering on the Alhambra which needed a fair effort at motorway speeds (as it should be). The Note, by comparison is very light. If you want 'heavy' try a Fod Galaxy with failed PAS, it took two of us (and I'm an ex-second row) to turn the b^&^&(y wheel!
the steering on a note is electric assisted, it could be as simple as a blown fuse or as expensive as an assistance motor, as others say, unless the dealer fixes it then walk away, you dont need extra expense, a fuse is pence,,,,the motor i would assume would be into the 3 figures area....
if you do still buy the car, make sure you get a warranty that covers the steering
