Here is what TopsOnline customers are saying...

Got the boot on Vic and it looks so much better than that old black one did. The fit is very good and snug. I like the way you added just a tad of material to the little pockets behind the seats that cover up the convertible frame corners. They look very nice, a smooth finish and went on very easy. All in all my friend I am very pleased with your work. Well done. You have my recommendation for high quality materials, excellent craftsmanship and fast courteous customer service. Five stars. Please feel free to use my name in your advertisements anytime.
