Motorists would rather pay more tax than lose the place in the corporate pecking order conferred on them by their company cars. And it is the company car — which accounts for half of all new motor sales each year — which continues to be the key method of measuring your progress up the greasy pole. Although a Roll-Royce or Bentley is the ultimate success symbol, a Jaguar is still desired by most top directors, according to the survey by top people’s pay and perks experts at the Monks Partnership.About 40 per cent of company cars are perks rather than necessities for the job, even though the average company car driver with a 1, 500cc engine is paying more than three times as much in tax compared to a decade ago. Average cash allowances for a company car rise from ￡1,500 for those whose job requires them to have four wheels, to ￡4,000 for chief executives.
