Not very DIY but I bet this group has the answers.
I'm looking for a low-cost way to get four people and their skis to the airport, in a normal hatchback. Looking at roof bars, they're about £90 a pair and they're specific to one model of car so not as much use as they might be.
Then I found the "Handirack"...
Has anyone used a Handirack? Does it really work? What are the disadvantages?
