Concept Car of the Week: Mercury El Gato (1970)

Of all the brands that marked American automobile history, Mercury had never been the most popular or the most loved, which ultimately led to its demise in 2011 when Ford chose to terminate the brand. To be fair only a handful of Mercury models are worth remembering: the 1950 Mercury Eight iconic base for custom cars, the 1955 Montclair, the Mustang-based Cougar, the Marauder X-100, the evil Cyclone Spoiler. However one of their coolest creations is fairly unknown mostly due its short concept car life: El Gato, in Spanish translating as "The Cat".

Mercedes C 63 AMG Edition 507: Price from £66,960

Available as Saloon, Estate or Coupe, the C 63 AMG Edition 507 will cost from £66,960 (for the saloon) and £68,160 (for the estate and coupe), or at least it will until you start to bother the options list. But for the base price you do get a fair bit already, with the AMG Drivers Pack as standard – which gives you extra horses (500bhp) and a higher top speed (174mph) and a free day out at an AMG BASIC Training Power and Passion Event so you can learn to drive your new C63 properly. As well as the extra power and freebie outing, you also get a selection of cosmetic and equipment teaks to the standard C 63 AMG including 19″ AMG Cross-Spoke alloys, composite brakes with red brake callipers, AMG bonnet with power dome and gloss black air vents and gloss black highlights for stuff like the mirrors and grill.
