What we drive: 1969 Triumph TR6

Updated March 2013: Go straight to the update here. Wisdom borne of experience: If you are contemplating the purchase of a British car and the vital parts of that car are in more than, say, two cardboard boxes, your purchase is suspect. Obviously there are exceptions: The D-type Jaguar comes to mind.

New Mercedes S 63 AMG costs from £119,565

New Mercedes S 63 AMG (pictured) costs from £119,565 The arrival of the new Mercedes S-Class in May saw MB move their range topper on properly for the first time in almost a decade, but with UK prices staring from £62,650 for the S 350 BlueTEC it wasn’t going to be on most people’s shopping list. And if you can’t afford Mercedes’ entry-level S-Class there’s no hope of affording the new S63 AMG, which Mercedes has revealed will cost an eye-watering £120k when it arrives in the UK in November. To be entirely fair, the new S63 is an awesome car with immense performance (which would be even more impressive if Mercedes endowed it with 4WD, as they do in other markets) with its 5.5 litre bi-turbo V8 developing 577bhp and getting the S63 to 62mph in 4.4 seconds.

Lexus LS (EU version)

The fifth-generation Lexus LS is the latest full-size luxury sedan to wear the badge since Toyota's premium brand was introduced in 1989. It continues the model's gentle evolution, this latest version reflecting the brand's L-finesse design language.  This is best seen in its inverted trapezoidal 'spindle' grille and L-shaped DRLs. The EU model measures in at 5,090mm long – 30mm longer than the outgoing model – while the wheelbase remains 2,970mm in length. The front and rear overhangs have increased by 10 and 20mm respectively.
