It is offered on Bring a Trailer by a dealer with bidding at $41,000 and two days remaining. The hook is a genuinely low-mileage car in arguably the most desirable specification these came in.2018 Alfa Romeo Giulia QuadrifoglioBring a TrailerWhat it's worth right nowThe Giulia Quadrifoglio has become an enthusiast favorite, and clean examples hold up well. According to Classic.com, the Quadrifoglio averages about $43,840, while Cars.com reports a 2018 nationwide average near $38,180, with most cars trading from the low $30,000s into the mid $40,000s and the rarest special editions higher. This car was originally stickered at $91,670.AdvertisementAdvertisementThe specification is what separates this one. It has the two options enthusiasts specifically hunt for: the roughly $8,000 Brembo carbon-ceramic brakes and the roughly $2,750 Sparco carbon-fiber bucket seats, plus a carbon steering wheel and the premium Rosso Competizione Tri-Coat paint. Owners in the listing's comments repeatedly single out that combination as the one that makes a Quadrifoglio feel special, and at 11,000 miles, this is a low-mileage, single-owner car.2018 Alfa Romeo Giulia QuadrifoglioBring a TrailerAt $41,000 with two days remaining, the bidding is tracking around the market average despite the standout spec and low miles, so it should climb. Fair value for a car equipped and preserved like this realistically lands in the $42,000 to $52,000 range.Condition and detailsThe car is finished in Rosso Competizione Tri-Coat over black leather and Alcantara with red stitching, with carbon-fiber active aero, carbon interior trim, and the Sparco seats that owners praise for being both supportive and surprisingly comfortable. The 2.9-liter twin-turbo V6, developed with Ferrari expertise, produces 505 horsepower through an eight-speed automatic and a torque-vectoring differential. The seller reports paint-meter readings with full paint-protection film on the front and original readings elsewhere.2018 Alfa Romeo Giulia QuadrifoglioBring a TrailerThe maintenance picture is reassuring for the model. Recent service has addressed several known Giulia items, including the serpentine belt, fuel pump, an oxygen sensor, a coolant flush, and fresh spark plugs, which is exactly the kind of proactive work that makes these cars less daunting to own. The Carfax is clean with no accidents and a single owner.2018 Alfa Romeo Giulia QuadrifoglioBring a TrailerTwo considerations are worth noting. The Carfax lists at least one open recall to be cleared, and Alfa dealer service can be costly, so several owners recommend finding a competent independent shop. The carbon-ceramic brakes are a highlight but are expensive to replace if ever needed, though the low mileage means that is a distant concern.The offerSpecificationDetailMakeAlfa RomeoModelGiulia QuadrifoglioYear2018Mileage11,000 milesEngineTwin-turbocharged 2.9-liter V6Power505 hp and 443 lb.ft of torqueTransmission8-speed automaticDrive typeRear wheel drive with torque-vectoring differentialExterior colorRosso Competizione Tri-CoatInterior colorBlack leather and AlcantaraCurrent bid$41,000, with two days leftInterested in this 2018 Alfa Romeo Giulia Quadrifoglio? View the listing here.What makes the Giulia Quadrifoglio uniqueThe Giulia Quadrifoglio was Alfa Romeo's return to the heart of the sports-sedan segment, and it announced itself by beating established German rivals at their own game. Its 2.9-liter twin-turbocharged V6 was engineered with Ferrari input and produces 505 horsepower, enough for genuine supercar-adjacent acceleration, while the chassis delivers the kind of steering feel and balance that reviewers and owners consistently describe as class-leading.2018 Alfa Romeo Giulia QuadrifoglioBring a TrailerAdvertisementAdvertisementMore than the numbers, though, the Quadrifoglio is celebrated for its character. It has a soul and an emotional quality that its efficient German competitors can struggle to match, and with Alfa Romeo's future increasingly electrified, the naturally charismatic, combustion-powered Quadrifoglio is already being viewed as a modern enthusiast's keeper. Well-specified, low-mileage cars sit at the front of that appreciation.My takeThis is a hugely appealing car, and the specification is the whole story. The carbon-ceramic brakes and Sparco seats are exactly the boxes seasoned Quadrifoglio owners say you want ticked; the Rosso Competizione paint is stunning; and 11,000 miles on a single-owner car with proactive service history make this an unusually strong example of a car that can otherwise carry reliability question marks.I would place fair value in the $42,000 to $52,000 range, so the current $41,000 bid looks like value with room to climb given the spec and miles. The practical notes are short: clear the open recall, line up a good independent Alfa specialist for future service, and review the maintenance records to confirm the known items have been handled, which they largely appear to have been. Do that, and this is one of the most soulful performance sedans of its era in close to its best form.Disclaimer: This post is for informational purposes only. We are not a dealership or broker.
