I bought a transit and I got the insurance very cheap with a company that specialise in motorcycle transporter insurance.
Mileage limit is 5k per year but very cheap, also no commuting in it.
£280 a year for me - 29 years old.
If you want to know who it is let me know.
I just felt the transit suited my needs better overall, bearing in mind that I can't take the car without leaving Ange and the kids stranded - a huge con for the trailer option.
