Yes, with its length of 4291 mm (169 inches), width of 1775 mm (69.9 inches), and height between 1280 to 1320 mm (50.4 to 52 inches), the Porsche 911 Coupe (Type 930) generally fits comfortably inside a standard single-car garage. Typical garage door widths and depths accommodate this car's dimensions well, though it's always prudent to consider extra space for opening doors and maneuvering.

Compared to the Porsche 911 Carrera RS 2.7, the Type 930 is slightly wider and heavier, primarily because the 930 introduced turbocharging and wider rear wheels for better traction. While the Carrera RS 2.7 had a width around 1640 mm (64.6 inches), the 930 increased this to 1775 mm (69.9 inches), reflecting a more aggressive body stance. The length remained similar, but the 930 generally weighs more due to added performance components and reinforcements.

In comparison to other 1970s and 1980s sports cars, the Porsche 911 Coupe (Type 930) held a relatively compact footprint with its length of 4291 mm (169 inches) and width of 1775 mm (69.9 inches). It’s narrower and shorter than many contemporaries like the Chevrolet Corvette of the same era, which typically measured over 4500 mm in length and wider than 1800 mm. This compactness contributes to the 930’s renowned agility and sharp handling.

The Porsche 911 Coupe (Type 930) has a roof load capacity ranging from 35 kg to 75 kg (77 to 165 pounds), varying with specific versions and structural reinforcements. While the 911 is not primarily designed as a cargo hauler, modest roof-mounted loads such as a small luggage box or sporting gear are possible. Exceeding the recommended load may impact handling, vehicle dynamics, and could cause damage to the roof structure.

The height of the Porsche 911 Coupe (Type 930) ranges from 1280 mm to 1320 mm (50.4 to 52 inches), underscoring its low-slung sports car profile. This low height enhances aerodynamic efficiency but can slightly limit interior headroom, especially for taller drivers or passengers. Visibility is typical for sports coupes of this era, with a focused forward view and limited rear visibility due to the steep rear window angles.

The Porsche 911 Coupe (Type 930) marked Porsche's entry into turbocharged road cars, featuring a turbocharged flat-six engine which significantly boosted performance over the naturally aspirated predecessors. It sported wider rear fenders to accommodate larger wheels and tires for improved traction. Over its production span from 1975 to 1989, the 930 saw various mechanical improvements such as refined turbocharging systems, better suspension setups, and updated interiors, making it a highly sought-after classic sports car combining raw performance with distinctive styling.
