2024 Jeep Avenger Summit Mhev S-A 1.2L Hybrid electric (clean) · WA74 JCV

The 1.2-litre MHEV automatic should return around 47-50 mpg in real-world driving, helped by the mild-hybrid system that assists the engine under acceleration and allows engine-off coasting. Road tax is likely to be in the lower bands thanks to Euro 6 EA status, though the mild-hybrid Avenger does not qualify for the full low-emission benefits of a plug-in hybrid. Insurance should be checked carefully — the Summit sits in a higher insurance group than lower Avenger trims, and the unusual colour may slightly affect premiums or repair costs.

Routine maintenance costs are reasonable: the 1.2 turbo petrol is a well-proven Stellantis unit, with oil services typically costing around £200-£300 at a main dealer. Budget for replacement brake fluid every two years and consider a cambelt check at higher mileages, though the 1.2 unit is generally chain-driven. Estimated annual running cost: £1,200-£1,500 covering fuel, tax, insurance, and a basic service, though this will rise if the vehicle is used primarily for short urban trips where the MHEV system adds less benefit.

Focus your inspection on areas where a near-new car can still present issues. First, check the 48V mild-hybrid system operation — the car should start smoothly and the MHEV assistance should feel seamless during gentle acceleration. Any warning lights, hesitation, or rough running could indicate battery or inverter issues that would be expensive to resolve outside warranty. Inspect the 12V battery condition, as these can deteriorate on cars that have sat on forecourts for extended periods.

Examine the bodywork carefully for stone chips, parking dents, and panel alignment — the bright yellow finish will show every imperfection and any remedial paintwork is difficult to match perfectly. Check the alloy wheels for kerb damage, as Avenger Summit wheels are larger and more expensive to refurbish. Inside, test all electrical systems including the infotainment screen (look for dead pixels or software glitches), climate control, heated seats if fitted, and all USB-C ports. The automatic gearbox should change smoothly with no hesitation or jerkiness, and a road test should confirm the MHEV system delivers expected fuel savings.

Finally, confirm that all Summus-specific equipment is present and working, including the rear-view camera, front and rear parking sensors, adaptive cruise control, and any driver assistance systems. Verify the service book is stamped or digitally recorded, and ensure the vehicle is HPI clear with no outstanding finance or insurance write-off history. As no MOT data exists yet, a thorough pre-purchase inspection by a Stellantis-trained technician is the single most important step before committing.
