Hello eaka2007, have this roofbox on an 06 Honda Civic, takes about 15 to 20 minutes to fit. Is aerodynamic and has had little effect on the fuel enonomy. Great for longer items, suited me perfectly and have found to be robust and has taken a 'tad' more than the recommended load without any problems, distribution of the lighter items at the ends recommended due to the lenght of the box. Friends have borrowed the box too without issue. Good budget box, recommended. Jara13
