Factory character
The factory details buyers are actually trying to keep intact
Factory Equipment
U.S.-market E36 M3 factory equipment guide
The U.S. E36 M3 combined M-specific drivetrain and chassis hardware with a relatively concise option list. Body style, gearbox, Luxury Package equipment, upholstery, and retained factory pieces now do most of the specification sorting.
Engine focus
The motor that defines the whole equipment story
Core M hardware
S50 or S52 inline-six
1995 U.S. cars use the 3.0-liter S50B30US; 1996-1999 cars use the 3.2-liter S52B32.
Manual or automatic
The five-speed manual anchors the enthusiast market, while factory automatics belong to a separate value lane.
M chassis specification
M-specific suspension, brakes, steering, wheels, seats, and bodywork should still form one coherent factory package.
Options and identity
Body style
Coupe, sedan, and convertible availability changed by model year and each body style needs its own comparison set.
Luxury Package
Luxury Package cars trade the more overt lower body treatment and some cabin details for a quieter specification; verify the original package rather than inferring it from swapped trim.
M cloth / Amaretta or Nappa leather
Upholstery is a meaningful originality signal because worn cabins are often retrimmed or converted during restoration.
