Just picked up a Viva yesterday. This car has been off the road since 2007. The last 5 years were spent in a hay barn, so I guess that makes it a Barn Find.
The story I got when I bought the Viva was... The original owner from new only drove it to work at the local Council and home again and then once a week to get his groceries, so it had low mileage. He stopped driving it in 2007 due to old age and it sat unused in his carport for about 5 years.
After the original owner died, the mechanic that had been doing the regular servicing of the car bought it and transferred the ownership into his son's name expecting his son to learn to drive in it when he was old enough and stored it in the barn.
It sat there in the barn for 5 years, but his son learnt to drive in a different car.
So now I have a 81,000 mile completely original condition HC Viva with one owner... two counting the mechanics son who didn't actually use it.
I checked out the online records for the car and this backs up the story given to me with the ownership history and recorded mileage between the 6 monthly Warrant of Fitness checks and registration required to keep cars legally on the road here in New Zealand.
