Photorealistic interior photograph of a private modern car showroom inside a house, about 14 by 9 metres. A polished pale stone floor reflecting four cars: two elegant 1950s and 1960s British grand tourers in dark green and silver, with plain oval grilles, round headlamps and smooth bonnets carrying no badges, emblems or wings, and two modern sports coupes in grey and black with plain grilles and no badges. The cars must not resemble any one recognisable manufacturer; they are generic, invented designs. Charcoal plaster walls, gallery track spotlights aimed at each car. On one side, a full wall of frameless glass with black steel edges looking out onto a sunny courtyard street with birch trees. On the far wall, two tall stone arches with heavy oak cart doors and black iron strap hinges. A brushed metal wall with five plaques reading BRISTOL, JENSEN, ALVIS, DAIMLER and ARMSTRONG SIDDELEY in plain lettering. Two leather club chairs and a side table, and a black steel workbench with a neat tool wall in one corner. Style: high-end architectural photography, gallery calm. Avoid: car brand badges, winged emblems, logos, any recognisable real car model, clutter, people, other text.
