If you pop down to your local Halfords, they have a flip chart in the roof bars area, detailing which roof bars they sell that will fit (Halfords, Paddy Hopkirk & Thule), and for Thule, which fixing kit is required, as well as the length of the bars needed for your vehicle. I used Thule Bars on a Xantia estate and they were noisy - because of the adjustment slots under the bar - Tape them up and it cuts down wind whistle. Thule Roof bars will normally support 100 KG which is no better than Paddy Hopkirk (Cheaper Bars)
