Who makes the best tops for our cars?

 

That is strictly a matter of opinion. What kind of top; vinyl, cloth, canvas? The type of material might make a difference.

In all honesty, what I would do is ask around in your local area for the best place to get a top installed. Any reputable installer will have a wide range of options; material, color, prices. What is critical is getting the top to fit properly. Unless you have done it before, it is not a DIY project, IMHO.
