This is the most powerful and proven fastest B9 S4 Avant in the country. It's a properly well-sorted car with absolutely no expense spared.Super-sports full Electric heated, massaging front seatsMemory SeatsVirtual CockpitHeads Up displayBang & Olufsen StereoMatrix LED headlightsCarbon Atlas interiorAdvanced key (keyless entry and hands free boot opening)These are just a few of the extras with the car. The heads up display is extremely rare to find.The car benefits from full service history and has had an extra oil change between services for good measure as I always service my cars every 5k. Last service in the history was a 23k, which is when I bought the car from Ascot McLaren, and she had a full service and set of OE 245/35/19 Hankook Ventus S1 Evo tyres all round. It has had a further oil change since then, 2.5k ago.Engine:Littco L610 hybrid Turbo4 bar map sensors200 cell high flow catted downpipe034 Motorsport updated HPFPIntegrated Engineering air-box / intakeIntegrated Engineering Turbo inlet Revo front mount intercoolerFunk motorsport turbo blanketGFB Recirc ValveAquamist Water Meth injection 80/20 - one nozzle per bank and a charge pipe nozzle.Chassis:H&R 25mm lowering Springs13mm forge spacers all round and new boltsTransmission mount upgrade EBC blue stuff front and rear padsEBC performance drilled /grooved front and rear discsDot 4.1 performance brake fluidStylingFront Maxton Lip / splitterRear CT carbon gloss black diffuserFull detail and ceramic coat with Infinity Wax Synergy 2 year coating including wheels and barrels and glassInterior:OE MMI Car-Play and Maps updated to latest versionCan-checked OBD data displayAquamist monitoring gaugeWith the fitment of all of these parts, the car had an additional oil change, new genuine NGK plugs and coils. Liqui-moly 5W40 oil was used along with Ceratec engine treatment. I also replaced all lines to the turbo, not just the o-rings.The engine and gearbox were custom mapped by Unicorn Motor Developments in Stockport who are without question the best tuners for this platform.The car made a very healthy 600bhp and around 800nm of torque. The numbers sound great but the torque curve is phenomenalCar has been timed at 0-60 in 2.86 seconds and a standing quarter mile at 10.63. It is a seriously quick car.I am asking 27,500 for the car and there are not any of these cars with this spec and such low mileage. Over 10k in invoices for the work completed. HPI clear never damaged or financed. Next MOT due 06/02/2025, Full service history, Red, 5+ owners, £26,500
