HERTFORDSHIRE, England — Times may be tough in the global auto industry, but the crunch apparently has had little effect on the super rich. As proof, all eight of the $197,000 Caterham RS Levante supercars have been sold, the company announced on Thursday.The hand-built Levante has RS Performance's supercharged 500-plus-horsepower 2.4-liter V8 engine, tucked into a modified version of the lightweight Caterham SV chassis.The company said that 'All new owners of Caterham RS models are required to attend a two-day advanced driving course on delivery of their machines.''The fact that all eight Levantes have been sold so quickly comes as no surprise,' said Andy Noble, Caterham sales and marketing director, in a statement. 'Over the last 51 years, the Seven has created and met the demand for those searching for the purest form of driving available. For drivers looking for the ultimate, the Levante facilitates that by taking Colin Chapman's original design to a staggering new level.'Inside Line says: The recession hasn't put the brakes on spending for those lusting after a Caterham RS Levante. — Anita Lienert, Correspondent
