Excellent pre visit correspondence about our needs, excellent service on site by Charlie. Very pleased with the roof bars and cycle carriers and even happier that he fitted them,small charge, as it would have taken me ages to do. Highly recommend

Brilliant company, did everything on messages as the travel distance was too far, first set of bars were a little bit too small, Robin sorted me out with a larger set, got them posted and organised pickup of the other set.
10/10 in my opinion
