About the 1998 CATERHAM 7
The 1998 CATERHAM 7 is a family car with a 1796cc petrol engine. 37 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 16% of all 1998 cars for reliability.
With an average of 23,524 miles at 28 years old, CATERHAM 7 owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.
1998 CATERHAM 7 Fuel Costs
The 1796cc petrol engine offers a reasonable balance between performance and economy. Expect around 36 mpg in mixed driving, which works out to roughly £1,327 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).
What does it cost to own a 1998 CATERHAM 7?

Buying a Used 1998 CATERHAM 7
At 28 years old, the CATERHAM 7 is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. Note: with only 37 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 1998 CATERHAM 7's fuel type, age, and engine size, these are the most likely problem areas to check.
Timing Chain / Belt
Watch outAt 28 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.
Rust and Corrosion
Watch outAt 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.
Suspension Bushings
Watch outRubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
