A 52-year-old Triumph Herald, which has just 20 miles on the clock, is expected to raise thousands when it goes up for auction this Saturday.
The navy blue saloon car, which was originally styled by celebrated designer Giovanni Michelotti, hasn't seen the road since the it left the factory, being in absolutely mint condition with such little mileage showing.
It even wears its original tax disc from 1961, which would have cost £15 at the time.
The car is to go under the hammer at East Anglian Motor Auctions in Norfolk and is expected to raise between £12,000 and £15,000 – a far cry from the Herald's £700 price tag when it left the Triumph factory in Coventry 52 years ago.
Auctioneer Tristram Belemore-Smith detailed the car's history: "The car dealer sold the Triumph Herald to a lady customer in 1961 and it was delivered to her home on a trailer," reported the Telegraph.
"Some years later he got a phone call from the family to say the lady had passed away and would he like to buy the car back?
"When he went to see it, he discovered it had not been driven from the day it had been delivered brand new - and decided to keep it as part of his private collection."
