Q: What is the cheapest best way to put this right???? I want the ride to be much softer with better road handling...

A: I think this is about the suspension. And if the drive is hard and uncomfortable it's probably got a sports suspension. Which will give you more control and round the bends and speed of the mark, but you pay for it with feeling every pothole. I had the same problem with my Honda Civic Sport. It's nothing to do with the size of your wheels. I guess the only thing you can actually do is get your suspension changed to be soft instead of hard by your mechanic... But that defeats the whole point of the car.... And might not be cheap. Plus, the car surely won't be as safe as advertised because it's not designed to have a softer suspension. Basically, there's a reason for it having a hard suspension. Didn't you do a test drive?!?! If it really racks you off you're just gonna have to get a different car with a softer suspension (which is what I did eventually because it did rack me off after a year!!)
