Why it's the old abandoned Garbo showroom, formerly the old abandoned Ferrari showroom!
How this got built in the green belt no-one knows.
But don't worry - you can still buy a Ferrari (or Porsche or Maserati or Aston) at the garage in the centre of town, or the one near the Wilmslow Garden Centre.
The showroom was reborn as "Garbo" - a deluxe clothes shop - which has now also closed. Garbo has relocated to the shopping centre at Summerfields. The former showroom is now offices.
