I bought this on a whim last year and put it together but have never actually used it! I've got the original box so it can be packaged up again if needed.
This is a lot sturdier than most bike carriers that fasten on with adjustable straps as it actually attaches to the car with flexible metal brackets.
This is currently on offer in Halfords at £117 but normally retails for £140. Priced to sell.
