Most of us have Fully Comp insurance with a "free" replacement car in the event of a non-fault accident right? Well go get your Policy and carefully check the wording cos the "free" car comes at a cost!
Unfortunately some "rather silly male driver" took it upon themselves to suffer "temporary colour blindness" and jump a red light ploughing right into the side of my cab. I rang my insurance co and was promised a replacement vehicle the following day - lovely! NOT!
The hire car was delivered on time and sparkly clean only it wasn't big enough

it was an Astra Estate which our LO say is too small to be a Taxi. Rang the Hire co - they told me that they could only supply that size vehicle; rang the insurance co and was told they would have to look into it; several phone calls later and the hire car is replaced - at last I can go out to work ... I wish
What I hadn't banked on was having to 1. MOT and Compliance Test the Hire car at a cost of £80; 2. have the Meter re-calibrated at a cost of £60; 3. have my Plate transfered to the Hire Car at a cost of £50; 4. have all my datahead / radio etc transfered at a cost of £180
I faxed all the receipts to the Insurance co's and got told that these were uninsured losses and that I can't claim for them grrrrrrrrrr!
I later found out that if I'd refused the Hire car and just rented another taxi locally for £150 a week this would have been paid without question. Check your Policy and don't get caught out like I have been.
