i used quote me today, part time trader, mostly mechanical work.
had a crash last year, my fault, had 7 years no claims before the crash and now is costing me £1200 a year, bad insurance area sadly, but that covers me fully comp on four of my own vehicles and any others not owned by me.
this also covers the misses to drive anything too.
it was cheaper to do this than seperate policies, that actually don't cover you to drive other cars as such, as driving another car is only a temporary situation, not so you can drive another car all the time, times of neccesity only.
