Kudos to whoever spec'd this one out new!July 30th, 2026 at 2:52pm ESTtorque_vector (9) Seller 2One hour left. Genuinely appreciate every question, comment, and bid — this has been a great process to watch unfold. For any last-minute questions before close: I'm here, phone in hand, will respond within minutes. Happy to jump on a FaceTime call for any serious final-hour bidder who wants a live look at anything specific. Whoever brings her home — you're getting the last true V12 S-Class, in a spec that took real intention to build. Enjoy her. Thanks all.July 30th, 2026 at 2:30pm EST$45,000 bid placed by @akshaypunwatkarJuly 30th, 2026 at 2:06pm EST$40,000 bid placed by @GkalldayJuly 30th, 2026 at 1:18pm ESTtorque_vector (9) Seller 1@rhartsough1 Fair take on preferences — color is personal. I prefer black interior and got this because it has black lining everywhere, include the floor which makes it look sharper. For context, the interior is Porcelain (585), not pure white though, in exclusive Nappa leather which handles wear better than standard leather. The photos are honest — the cabin shows normal wear consistent with 82k miles and is far from "yellowed." I already took shots in different lighting, sunny, cloudy, inside the garage, etc. Walk through video reflects how it looks with low lighting. Happy to send close-up shots to any serious bidder who wants to evaluate the actual condition.July 30th, 2026 at 1:07pm ESTrhartsough1 (3) 0If this were blue or black - with a black interior — it’d be tempting. As is the white interior is so bad…it ages so poorly. Already looks yellowed. Will never understand why Mercedes has made so many cars with white leather. Ages poorly and impossible to clean without destroying the dye. July 30th, 2026 at 12:41pm ESTtorque_vector (9) Seller 2@akshaypunwatkar Great, specific question. Pulling directly from the RENNtech invoice What's installed: RENNtech ECU Upgrade for the W222 S65 V12 BiTurbo (Item Code 54.222.S65BT, ECU serial me09048) RENNtech TCU Upgrade for the 722.9 seven-speed (Item Code 27.722.9.TS) RENNtech HSM (Handheld Suspension Module) OEM M275 V12 air filters (installed with the tune) This is RENNtech's software-focused package for the M279 — ECU + TCU + HSM. The invoice reflects that. The TCU tune is worth calling out specifically because on the M279 the stock 722.9 has a torque limiter that throttles the ECU tune's output — the TCU upgrade unlocks that ceiling, which is why RENNtech pairs the two. RENNtech quotes 670 hp / 840 lb-ft for this specific package on the M279. I don't have a dyno sheet on this car, so I'm citing RENNtech's published figures rather than measured output. The reason for not doing more hardware is to not risk the car to fail CA's strict inspection and emissions and not to mess with the factory AMG cats which are actually produce a better sound. The car passed NYS state inspection and emissions without an issue.July 30th, 2026 at 12:32pm ESTakshaypunwatkar (0) 0Which specific RENNtech package is installed on this S65? Need to know if it’s strictly an ECU tune or if it includes downpipes, blow-off valves, or intercooler pump upgradesJuly 30th, 2026 at 12:29pm EST$37,500 bid placed by @akshaypunwatkarJuly 30th, 2026 at 11:58am EST$37,000 bid placed by @GkalldayJuly 29th, 2026 at 4:49pm ESTtorque_vector (9) Seller 1@hasib32 No vibrations at high speeds. It also got a wheel alignment at the dealer (it's in the records). The care is very stable and wobbling or anything. Due to CCBs, the rotors are not warped, so braking is ultra smooth, that's the best part of this car. The car is heavy but braking is so good, plus no brake dust on the wheels. Thanks for bidding!July 29th, 2026 at 4:46pm EST$35,000 bid placed by @hasib32July 29th, 2026 at 4:45pm ESThasib32 (0) 0Nice car! Haven’t seem this spec anywhere! Any vibrations at high speeds, is the steering stable at high speeds? Thank youJuly 29th, 2026 at 3:33pm ESTtorque_vector (9) Seller 0Thanks to everyone who has taken time to look at the car, ask questions, and bid — genuinely appreciate the engagement. With 24 hours left, a few quick notes: On rarity: From my searching, I'm not seeing another W222 M279 S65 currently listed on BaT, Cars & Bids, or the major auction platforms — please correct me if I've missed one. These cars come to market rarely, and RENNtech-documented examples with this option stack are rarer still. On the Carfax: For full transparency, the Carfax shows three damage events across the car's life — the June 2019 deer strike I described earlier (front and right front, categorized as "minor to moderate," repaired at MB of Encino), plus two minor damage reports in October 2020 and January 2022 during prior ownership -- no info or collidion repair on them from the dealers. Structural, airbag, and title-brand checks are all clean per Carfax. Under my ownership: zero incidents. For questions: Happy to answer anything in the comments, via DM, or over a FaceTime walkaround if that helps. I'll be responsive through the close of the auction. Thanks again for the interest.July 29th, 2026 at 3:25pm ESTtorque_vector (9) Seller 0@NewAge I don't have them. Only information I got from the respective dealers. No written records were shared due to client privacy. However, the first was confirmed as deer strike and the other two were no
