Ally,
After me family, only have 2 other passions me car and me mountain biking specially Kona's.
Been mountain biking for longer than I care to remember and now me boys are getting better than me, bugger!!!!
At this stage not put any bikes on me car, we are lucky enough to live very close to some excellent downhill, dirt jumping and cross country tracks.
Tho at some point we are going to have to go further afield. With all the other cars I have owned have always gone for a manufacturer roof based bike rack system, have always assumed that Seat would do such as system.
Hope I'm not wrong.
