The latter meant a more powerful 5.4-liter V8 breathing air from behind that classic grille. The unit made 432hp, which translated into a 0-60mph (0-96km/h) run in less than 6 seconds and a top speed of 160mph (258km/h).
In addition to having a few extra horses available on tap, the V8 Vantage Volante X-Pack was also equipped with a new bonnet, extended front spoiler, flared wheel arches and boot spoiler.
The example shown here was manufactured in 1986 and was actually used by Aston Martin as a show car for the Earls Court Motor Show. Its status is highlighted by the special plaque mounted on the center console, and after the event, it was registered in 1987 and kept by the factory before being sold to one of the three owners.
Since 1990, the car has been in the possession of a collector, who took great care of it and spent a small fortune on every work that was required, including £9,000 ($11,852) for a paint refresh back in 2008. More recently, it received a major service that saw the installment of a new clutch.
Despite turning 32 this year, this classic Aston Martin has less than 32,000 miles (51,499 km) on the clock.
Silverstone Auctions estimates that it could fetch between £280,000 and £320,000 ($368,719-$421,393) at the event that takes place at the Silverstone Track in the UK on July 21 and 22.
