I have these because my Shelby is lowered and they are perfect. My garage floor is coated but they don't move when I start to drive up on them. and the best part is once on them you remove the ramp part so you can get under it. I had to also buy the extension which adds another 3 feet to the ramps for the mustang but the fiesta I don't need the extra angle. They are light weight and a little expensive but to me well worth it. Have had them for about 5 years and no issues. I got the 67 inch 2 piece but the 56 inch
one piece would be fine for the fiesta.
