6x2.co.uk

[Robbie]

I picked this domain up as many people know in the UK - A 6x2 is type of tractor unit (big rig) it is called a 6x2 or 4x2 it concerns the wheel base of tractor unit!

I want to know domains like this 6x2.co.uk are they popular? Should I register more names like this or leave it?

Do others own names like this? Do you think anyone apart from a truck manufacturer would want a name like this?

Thanks,

Rob
