“There is a crank hub issue, but so far mostly on modded cars with DCT. A couple cheap fixed/precautions that you can take.”clubracer6 · Jan 17, 2023 at 2:38 PM

• The press-fit crank hub: the signature S55 concernmechanical
  The factory press-fit crank hub is the most-discussed S55 weak point, able to slip the timing gear on high-torque or tuned cars (commonly cited past ~525-550 WHP) with damage ranging from a CEL to piston-to-valve contact; most owners treat it as overblown on stock, unabused cars, but bidders still routinely ask whether it has been addressed. …
• S55 reliability and dependability reputationownership
  Long-term owners describe the F80 as among the most reliable M3s ever, with high-mileage and even 500-600hp examples running trouble-free and stock/lightly tuned cars needing no more than normal 3/4-series maintenance aside from a few engine gaskets in the 70-100k range. …
• S55 twin-turbo character and soundmechanical
  The S55 twin-turbo inline-six is praised for pulling hard with linear, low-rpm torque that builds and holds into the upper range, and for a great exhaust note especially through aftermarket mufflers. …
• Preventive S55 service items: cam bolts, oil filter housing gasket, oil panmechanical
  Beyond the crank hub, owners tackle a cluster of known S55 items preventively—cam carrier bolts that can loosen and cause a cold-start tick, and the oil filter housing gasket and oil pan gasket that develop age-related leaks—none of which are on BMW's formal maintenance schedule. …
• Carbon-fiber roof haziness and clear-coat delaminationmechanical
  The exposed carbon-fiber roof can go hazy and its clear coat can delaminate under sun and heat, with some owners seeing failures and others (even in Arizona) reporting none; PPF/ceramic protection and carbon-look wraps are the common remedies. …
• Tuning headroom and reversible tunes (JB4, Dinan, flash)mechanical
  The S55 responds strongly to tuning, from plug-and-play JB4 piggybacks (roughly 20+ HP, toggled off from a phone) to reflashable Carbahn/BM3/MHD tunes and Dinan Stage 2 packages that push into the mid-500s while, in Dinan's case, retaining full factory warranty—and most tunes can be returned to stock, a point buyers probe as due diligence. …
• DCT vs 6-speed manualbuying
  The transmission debate is unresolved: some argue the DCT is the best BMW dual-clutch and the right pairing for the S55 (faster shifts, quicker on track), while others prize the manual for engagement and daily livability—and the manual carries a substantial and growing price premium. …
• Competition Package: dual personality and firmer setupvariant
  The Competition Package is praised for taking an already strong car and sharpening it into a Jekyll/Hyde machine—docile in traffic, aggressive on a closed course—with a firmer, more performance-focused suspension than the base adaptive-damper setup, plus factory cues like the black rear badge. …
• M3 CS: rare send-off variant, often confused with ZCPvariant
  The ~600-unit M3 CS is treated as a special limited variant with CS-specific muffler and softer springs than the ZCP, commanding roughly $50k-$75k in these threads; commenters note it is frequently and mistakenly conflated with the Competition (ZCP) package in listings, which suppresses awareness of what a real CS is. …
• Exhaust and suspension modifications, and EDC-retaining coiloversoriginality
  Owners commonly modify exhaust and suspension—keeping the exhaust valve permanently open (unplugged without a code), fitting aftermarket sound controllers, and choosing Bilstein/KW coilovers that retain factory EDC adaptive damping via OE connectors so the swap is fully reversible—while bidders work to distinguish comp, Akrapovic, and Dinan exhausts by muffler and sound. …
• Twitchy handling with traction control offownership
  Owners repeatedly warn that with DSC/traction control switched off the car requires real throttle control and will surprise the unwary, recommending caution unless conditions and skill allow. …
• Versatile daily-plus-track characterownership
  Owners praise the F80 as an exceptionally versatile sedan that handles the school run and daily commute yet turns into a track weapon, with several calling it their favorite M car and a weekly track car that never let them down. …
• Maintenance flashpoints: break-in service, brake fluid, spark plugs, over-rev loggingownership
  Records-focused bidders press on the early ~1200-1500-mile break-in service, brake-fluid flush intervals (disputed as opinion by a former-dealer seller), and spark-plug/oil history, and confirm the DME logs over-rev/redline events much like a Porsche—so an engine report is part of due diligence. …
• Market values and appreciation trajectorymarket
  Commenters describe F80 values as coming off the peak of prior years but leveling out and remaining strong—some seven-year-old cars selling near sticker—and note the same cars fetch notably more on BaT than on Cars & Bids, viewed as a premium-venue effect. …
• Rare colors and spec combinations command premiumsmarket
  Scarce Individual paint colors (Estoril Blue, Venetian Violet, Imola Red, Yas Marina Blue, Azurite Black) with low production counts, especially paired with a manual and desirable options, are repeatedly cited by sellers and bidders as premium-justifying selling points. …
• F80 styling preferred over G80: the last true-to-form M3market
  Commenters consistently favor the F80's looks and analog gauges over the newer grille-heavy G80, predicting the F80 will be remembered as the best-looking, last true-to-form M3—a design factor they treat as supporting values. …
• Manual scarcity and stock cars holding value bestmarket
  With only about 20% of F80s built as manuals and clean low-mile stock examples increasingly hard to find, commenters argue that stock or near-stock manuals with known service history will be the long-term most valuable, while heavily modified cars often signal abuse and lesser value. …
• Originality, accident, and OEM-vs-aftermarket scrutinyoriginality
  Bidders press hard on Carfax entries, paint-match and meter readings, and whether accessories are genuine M Performance versus 'M Performance-style' aftermarket pieces; one car's out-of-warranty engine failure and replacement drew heavy scrutiny over the failure mode and BMW's partial goodwill coverage. …
• Buying quirks: Canadian imports and pre-2018 equipment gapsbuying
  Cross-border buyers weigh import math (BaT fee, 2.5% duty, shipping) and a US requirement to swap the cluster to an actual MPH gauge face, while early F80s (pre-2018) lacked any backup camera or parking sensors—2018 being the first year a backup camera was standard. …
