Most standard garages have dimensions roughly around 2.4 meters (8 feet) in width and about 5 to 6 meters (16 to 20 feet) in length. Given the 1973 Mercedes-Benz /8 (W115 facelift) sedan measures 1770 mm (1.77 m or 69.7 inches) wide and 4680 mm (4.68 m or 184.3 inches) long, it will comfortably fit into a typical single-car garage with enough clearance for opening doors and maneuvering. However, tight garages or ones with limited width might require careful parking.

With a length of 4680 mm and width of 1770 mm, the Mercedes-Benz /8 (W115 facelift) offers comfortable seating for five passengers. Its classic three-box sedan design provides ample headroom and legroom, suitable for both front and rear occupants. The 1440 mm height supports a decent cabin vertical space, though by modern standards, interior space feels cozy but sufficiently ergonomic, reflecting the sedans of the 1970s that balanced exterior size and passenger comfort effectively.

The 1973 facelifted W115 /8 continued the established dimensions of its predecessor with only minor tweaks to styling rather than structural changes. The original W115 (pre-facelift) models, produced since 1968, had very similar measurements, with length around 4680 mm and width about 1770 mm. This consistency meant that the facelift focused primarily on improving aesthetics and refinement without changing the fundamental size, preserving interior spaciousness and road presence.

Compared to contemporaries like the BMW E3 and Audi 100s of the early 1970s, the Mercedes-Benz /8 W115 facelift sits comfortably within the executive sedan segment's typical size range. Its length of 4680 mm and width of 1770 mm are competitive, offering a balance of cabin space without being overly large. While some rivals stretched slightly longer or wider, the W115 distinguished itself with a reputation for build quality and comfort more than pure size dominance.

The 1973 Mercedes-Benz /8 W115 facelift is equipped with 5.5J x 14 inch rims. These relatively modest-sized wheels by modern standards help contribute to a smooth and comfortable ride by allowing the suspension to absorb road imperfections effectively. Smaller wheel diameters combined with higher-profile tires typical of the era improved cushioning and road contact, lending the car its classic plush driving feel.

The curb weight range of 1330 to 1430 kg (2932 to 3151 lbs) across the 1973 Mercedes-Benz /8 W115 facelift models is influenced by factors such as the engine type (diesel or gasoline variants), transmission choices, trim levels, and optional equipment like power steering or air conditioning. Heavier luxury or engine upgrades naturally push the vehicle's weight toward the upper limit, whereas base models remain lighter.
