Porsche Boxster S

With company car tax based on a vehicle’s CO2 emissions, there aren’t many who will take the plunge on a model as performance focused as Porsche’s Boxster S. However, the German firm has striven to boost the efficiency of its jaw-droppingly capable products, which means this first-class driving machine falls within a £500-per-month budget for business users.

The 3.4-litre mid-engined roadster delivers 316bhp to the rear wheels and 0-62mph in only 5.1 seconds. What’s more, the Boxster’s dynamic abilities make it one of the sharpest-handling production models on the planet.
