About the Audi RS4 Avant
First introduced in 2000, the RS4 Avant has evolved through three generations, each offering a compelling blend of family-friendly practicality and supercar-rivalling performance. The B7 generation (2006-2008) featured a naturally aspirated 4.2-litre V8 producing 420PS, whilst the B8 (2012-2015) increased power to 450PS with revised styling and improved technology. The current B9 model, launched in 2017, delivers 450PS from a twin-turbo 2.9-litre V6 and represents the most refined iteration yet.
All RS4 Avants feature Audi's quattro all-wheel drive system as standard, along with uprated brakes, sports suspension and aggressive bodywork including flared wheel arches. Interior appointments are suitably premium, with sports seats, high-quality materials and comprehensive infotainment systems. The boot offers 505 litres of space with the rear seats in place, making this a genuinely practical everyday performance car.
What Affects the Price
Generation is the primary price determinant, with B7 models starting around £8,000-£15,000, B8 variants commanding £20,000-£35,000, and B9 examples typically £35,000-£45,000. Mileage significantly impacts value, particularly given the performance nature of these vehicles - lower mileage examples with comprehensive service history attract substantial premiums.
Condition and maintenance history are crucial, as RS4 ownership costs can be substantial. Cars with complete Audi main dealer service history command higher prices, whilst those with missed services or outstanding mechanical issues sell for considerably less. Optional extras such as carbon ceramic brakes, dynamic ride control, panoramic sunroofs and upgraded sound systems add value. Colour combinations matter too, with desirable shades like Nardo Grey, Daytona Grey and Suzuka Grey proving more sought-after than common blacks or silvers.
Buying Tips
Insist on a comprehensive service history and check for evidence of regular oil changes, as the high-performance engines require proper maintenance. For B7 and B8 models, listen for rattles from the timing chain area and check for carbon build-up issues on direct-injection engines. Inspect the dual-clutch gearbox operation carefully - any hesitation, juddering or warning lights could indicate expensive repairs ahead.
Check brake condition thoroughly, especially on cars fitted with optional carbon ceramic discs which cost thousands to replace. Examine suspension components and bushes for wear, particularly on higher-mileage examples. Verify that all electronics function correctly and that the quattro system engages properly. Consider obtaining an independent pre-purchase inspection, and budget for running costs including insurance, fuel consumption averaging 20-25mpg, and servicing that can easily exceed £1,000 annually.
