A car uses more fuel when fitted with a roof rack because it increases aerodynamic drag, making the car work harder to overcome air resistance. The additional weight of the roof rack also adds to the fuel consumption by requiring more power to accelerate and maintain speed.
You can fit a roof rack in many different ways for different vehicles. Vehicles will either use fixpoint locations pre-drilled into the roof, use the securing points underneath the rubber door surrounds or secure on a vehicles pre-fitted roof rails. These pre-fitted roof rails normally run from front to the rear of a vehicle, allowing easy fitment anywhere along the rail. For a comprehensive guide of fitment, type Carracks.co.uk in to Google, you can see how it works and also where to buy the parts that you need for a roof rack.

Yes, ish! I fitted a gutter mounted 90 rack to a 200tdi discovery. I had to bend the legs out a little to get it on but it did go on. If its a full length 110 rack though it will be too long, in which case you can sell it to me because I need one! :D

It uses more petrol because of air resistance. Friction pulling the load on the roof which causes the car to use more petrol because of the weight it needs more energy to move around.
Its answer is very simple that a car uses more petrol when it has to overcome more wind resistance.

The entire rack is screwed into the roof of the SUV, up from the SUV roof into the rack. However, if you want to remove the 2 cross-bars, pop off the black plastic "half-cones" at the front of rack, and then the bars can be removed.
