This 2006 coupe goes further, with a Kenne Bell twin-screw supercharger bolted to its 4.6-liter V8 for a serious hit of extra power. It shows 15,000 miles and is on Bring a Trailer at no reserve, bid to $11,250 with three days to go, so it sells this week.2006 Ford MustangBring a TrailerWhat it's worth right nowThe Roush Stage 2 occupies an affordable and enthusiast-driven corner of the market. According to Classic.com, comparable Stage 2 examples generally trade in a range of roughly $14,850 to $25,076, with condition, mileage, and modifications driving where a given car lands.AdvertisementAdvertisementThis one is a mixed bag in value terms. Its low mileage and the added Kenne Bell supercharger boost its appeal and its performance, but the modifications detailed below, along with the missing documentation for the blower's tune, are the kind of thing that gives some buyers pause. As a no-reserve sale, the market will set the number.2006 Ford MustangBring a TrailerWeighing the low mileage and forced induction against the modification questions, fair value realistically lands in the $13,000 to $22,000 range, most likely the mid-to-high teens. At $11,250 with three days remaining and no reserve, the bidding is climbing and should push into that band.Condition and detailsThe car presents as a striking, purposeful build. Finished in Bright Signature Red with the full Roush aero kit, hood scoop, and quarter-window louvers, it wears chrome 19- and 20-inch wheels and stops via Wilwood six-piston front brakes, riding on Roush-tuned suspension. Inside are two-tone red and black leather seats with embroidered Jack Roush signatures, carbon-fiber dash trim, and an aftermarket Alpine audio system. The 4.6-liter V8 has been fitted with a liquid-cooled Kenne Bell twin-screw supercharger, a matching throttle body and intake, and shorty headers, driving through a five-speed manual to a limited-slip differential.2006 Ford MustangBring a TrailerSeveral modifications warrant real scrutiny. The Kenne Bell blower is a significant, non-factory power adder, but no dyno sheet or tune documentation was provided despite commenters asking, so confirm the tune, boost level, and that the car runs reliably before bidding, since forced induction raises the stakes on the engine's health. The factory catalytic converters have been removed, which is not emissions-legal in California and other states and is a real registration and resale consideration, and the traction control has been deleted via tuning, worth noting on a supercharged rear-drive car.2006 Ford MustangBring a TrailerTwo more items to check: a Carfax entry notes both airbags were replaced in 2023, so ask why, and the Carfax shows at least one open recall to address. The selling dealer's terms require payment by wire with no inspection contingency, so arrange any pre-purchase inspection before you bid.2006 Ford MustangBring a TrailerAdvertisementAdvertisementThe offerSpecificationDetailMakeFordModelMustang Roush Stage 2Year2006Mileage15,000 milesEngineSupercharged 4.6-liter V8PowerNot specified by the sellerTransmission5-speed manualDrive typeRear wheel drive with limited-slip differentialExterior colorBright Signature RedInterior colorRed and black leatherCurrent bid$11,250, no reserve, with three days leftInterested in this 2006 Ford Mustang Roush Stage 2?

Built on the S197 Mustang GT, the Stage 2 focused on handling, adding Roush-developed front struts, rear shocks, springs, and sway bars to the appearance and exhaust upgrades of the Stage 1, giving the car genuinely improved body control to match its menacing looks. The Jack Roush-signed seats and Roush instrumentation lend it a real sense of occasion.2006 Ford MustangBring a TrailerThis particular car adds an owner-installed Kenne Bell supercharger, one of the most respected forced-induction systems for the 4.6-liter modular V8, transforming the naturally aspirated GT's output into something far punchier. The result is a distinctive, hard-hitting pony car that stands apart from a standard Mustang GT in both attitude and pace.My takeI have a soft spot for cars like this, because they deliver a huge amount of muscle and presence for the money. A low-mileage Roush Stage 2 with a proper Kenne Bell blower, Wilwood brakes, and that signature aero kit is a genuinely fast and characterful pony car, and the no-reserve format means someone is getting it at a market-set price. For a buyer who wants supercharged V8 thrills on a budget, the appeal is obvious.AdvertisementAdvertisementFair value sits in the $13,000 to $22,000 range, with the low mileage and supercharger pulling one way and the modification questions pulling the other. So go in clear-eyed: get documentation on the supercharger tune, understand that the removed catalysts affect emissions compliance, clarify the airbag replacement, and arrange an inspection before bidding given the dealer's firm terms. Handle that, and you have a distinctive, hard-charging Roush that stands out at any cars and coffee.Disclaimer: This post is for informational purposes only. We are not a dealership or broker.
