What should I be paying?
The sensible diesels offer, for such a big saloon, near extraordinary efficiency on the official CO₂ cycle, returning as little as 105g/km. In a car this large? Wizardry (although relatively meek responsiveness does reveal the compromise...). That's good news for road tax, and though Skoda's claims of 60mpg-plus motoring may be a trifle ambitious, the Superb shouldn't sting you on running costs. Residuals shouldn't be VW Phaeton-style shocking, provided you don't get too lavish with the options list.
