Miles per pound (mpp)

Reliable fuel consumption data for comparison purposes is not available for this model.
What is miles per pound?
  • Can be quite cheap
  • Sensible mpg if driven sensibly
  • Only petrol. No hybrid or electric

What are the running costs?

This very much depends on which model you have. As Caterham only builds a small number of cars each year it doesn’t publish CO2 figures, but the Seven uses a Suzuki engine or, more commonly, modern Ford units. 

The 660cc Suzuki engine can prove really economical. You can expect mpg in the mid-50s in day-to-day driving, with a fair bit less if you’re really making the most of its performance. Ford engines come in different power outputs, but early to mid-20 mpg is achievable.

Residuals are incredibly strong providing the car is in good condition and insurance is unusually low given the performance the Caterham offers while parts prices and servicing are average.

Servicing and warranty

As this is a specialised bit of kit, service intervals are low. Every Seven requires a service after 1,000, 6,000 and 12,000 miles. While Suzuki engined models also require one at 3,000 miles

Caterham can provide pre-annual MoT checks and set you up with an MOT tester familiar with Sevens.


  • Relatively simple
  • Short service intervals
  • Good aftersales

Reliability is generally very good thanks to proven mechanicals, high standards of engineering and relative simplicity. It’s worth remembering the Seven is from a very small-volume manufacturer, and you’ll need to factor in the likelihood of teething problems and small faults along the way.

Home construction is an option, and this can affect the final build quality and subsequent reliability.
