I Draw Cars: The sketchbook that puts drawings into perspective

I Draw Cars is a project set up by Adam Hubers and Matt Marrocco – both CCS graduates – to encourage designers young and old to pick up their pens and practice that most basic yet powerful tool in their kit: sketching. Their new book features over 100 pages of perspective underlays – from basic views right up to complex three-point – to use as templates with which to practice. Each underlay is printed in non-photo blue, meaning it won't be picked up by a scanner should you choose to drop it into Photoshop.

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.
