My 101 (landrover) has a reg date of '82, but all the 101 ambulances were built as GSs (general service - the soft top one) in the 70s.
They were then put into storage by the army, pulled out, and modified with hard biddies.
Given that the historic tax exemption thing is now rolling again (40yr) i figured in 7yrs mine would be exempt. 7yrs is quite a way off.
But...
Ive just been informed that they will go by the chassis date. Which will probably be around 40yrs ago now, or in the next few years.
That's a bit of a bonus. I was planning on taking it off SORN this year anyhow, so ill be looking at the detail more closely now.
If i could get cheap insurance on it (which it seems i cant) it would be very cheap motoring indeed.
