Finished in a striking Firemist Red Metallic over Charcoal leather, it pairs a 493-horsepower supercharged V8 with a power-folding hardtop and genuine grand-touring luxury. As one of the great performance bargains of the modern era, offered with the sought-after P30 upgrades and 27,000 miles, it is an appealing open-top AMG, and it is offered on Bring a Trailer.2006 Mercedes-Benz SL55 AMGBring a TrailerWhat it's worth right nowThe R230 SL55 AMG spans a wide market, but the P30 cars sit at the stronger end. Classic.com shows typical SL55 examples trading from around $18,000 into the $40,000s with a nationwide average near $34,000, while the rarer P30 Performance Package version commands a premium, with guides placing average P30 values in the mid-$30,000s and the best cars higher. This is a well-optioned, comparatively low-mileage P30 car, which supports a result toward the upper part of the range.2006 Mercedes-Benz SL55 AMGBring a TrailerGiven the desirable and rare P30 Performance Package, the low mileage, and the standout color but accounting for the deferred maintenance items and the well-known running costs of these cars, I would call fair value roughly $28,000 to $40,000. The current $22,750 bid with seven bids and six days remaining is below that and should climb, with the final figure reflecting how buyers weigh the P30 rarity against the maintenance ahead.Condition and detailsThe specification is genuinely strong. This SL55 is finished in Firemist Red Metallic over Charcoal leather with the P30 AMG Performance Package, which added a limited-slip differential, a second oil cooler, larger brakes, a revised "F1 safety car"-style front fascia, a raised 186-mph limiter, and revised Active Body Control settings, plus the Premium 1 Package adding ventilated seats and Keyless Go. The supercharged 5.4-liter M113 V8, factory-rated at 493 horsepower, drives through a five-speed automatic, and the car has a power-retractable hardtop, a Designo Alcantara headliner, and Bose audio.2006 Mercedes-Benz SL55 AMGBring a TrailerFor condition, this is a 27,000-mile car with a clean Carfax, approximately 7,000 miles added by the current owner since 2018, dealer-maintained throughout. The disclosed and recommended items are worth noting: the Sensotronic brake system was bled in March 2024 with front and rear brake service recommended at that time, the starter battery was replaced then with an alternator replacement recommended, and the windshield washer fluid sensor needs replacement.2006 Mercedes-Benz SL55 AMGBring a TrailerAdvertisementAdvertisementThe diligence on an SL55 is about budgeting for its known costs. The comment thread was a useful guide, with owners noting the tires carry 2017 and 2018 date codes and need replacing, the P30's large two-piece front rotors are expensive, and estimates for the recommended alternator and full brake service run several thousand dollars at an independent shop. Have a Mercedes specialist assess the ABC hydraulic suspension, the brakes, and the alternator, and budget accordingly. This is a private-party sale with a clean Connecticut title.2006 Mercedes-Benz SL55 AMGBring a TrailerThe offerSpecificationDetailMakeMercedes-BenzModelSL55 AMG P30 (R230)Year2006Mileage27,000EngineSupercharged 5.4-liter M113 V8Power493 horsepower, 516 lb-ftTransmissionFive-speed automaticDrive typeRear-wheel drive with limited-slip differentialExterior colorFiremist Red MetallicInterior colorCharcoalCurrent bidUSD $22,750Interested in this car? View the listing here.What makes the SL55 AMG uniqueThe R230 SL55 AMG was a landmark car, the first SL of the 21st century to receive the full AMG treatment, and it turned Mercedes' elegant folding-hardtop roadster into a genuine autobahn stormer. Its supercharged 5.4-liter M113 V8 is one of the most revered engines AMG ever built, a torque monster renowned for both its ferocious, effortless thrust and its bulletproof reliability, capable of humbling many purpose-built sports cars of its era while delivering that muscle through the comfort and refinement of a luxury Mercedes. It was, and remains, an enormous amount of performance and prestige.2006 Mercedes-Benz SL55 AMGBring a TrailerThe P30 AMG Performance Package elevates this example further, adding hardware and settings that push the SL55 closer to the mighty V12 SL65 experience, including a limited-slip differential, upgraded cooling and brakes, a raised top speed, and track-tuned Active Body Control. That ABC hydraulic suspension virtually eliminates body roll, giving these cars an uncanny blend of composed handling and cosseting ride. As values remain accessible for the performance on offer, a rare, low-mileage, well-specified P30 car in a standout color represents a compelling way into supercharged AMG motoring, provided its upkeep is respected.My takeThis is a lot of supercharged AMG for the money: a rare, low-mileage P30 Performance Package SL55 in a genuinely striking Firemist Red, combining monster V8 muscle with folding-hardtop luxury. My fair-value call is $28,000 to $40,000, reflecting the P30 rarity, the low mileage, and the standout color against the deferred tires, brakes, and alternator and the well-documented running costs of these cars, so before treating the current $22,750 bid as the entry point a buyer should have a Mercedes specialist assess the ABC suspension, brakes, and alternator, and budget realistically for the maintenance these AMGs demand.AdvertisementAdvertisementDisclaimer: This post is for informational purposes only.
