For a whole generation the 308 GTS is fixed in memory through Tom Selleck behind the wheel in Magnum P.I. (1980-1988). But the 308 GTB's story began in 1975, when Ferrari unveiled the successor to the Dino 246, no longer under the Dino badge but as a fully fledged Ferrari V8 model. Early production cars received fibreglass bodywork (Vetroresina, around 712 cars between 1975 and 1977), after which Ferrari switched to steel. Under the bonnet sat the F106 V8 mounted transversely behind the driver, first with Weber carburettors, later with Bosch K-Jetronic injection and finally with four valves per cylinder (Quattrovalvole 1982-1985). The 308 is therefore Ferrari's first regular production V8 Berlinetta and the car that opened the V8 era of Maranello, a lineage running via 328, 348, F355, 360, 430, 458, 488 and F8 through to today's 296 GTB.
Ferrari unveiled the 308 GTB in 1975 as the successor to the Dino 246 (1969-1974) and first regular production V8 Berlinetta from Ferrari. The Pininfarina design became iconic for the 1970s and famous through the Magnum P.I. television series (1980-1988, with Tom Selleck driving in a Rosso Corsa 308 GTS). The package includes naturally aspirated 3.0-litre V8 (Tipo F106 AB, shared with Mondial), manual five-speed gearbox, and mid-rear engine position. For collectors the 308 GTB represents Ferrari's first regular production V8 Berlinetta and classic Italian design icon.
The early production 308 GTB (1975-1977, around 712 cars worldwide) is built with fibreglass bodywork (Italian Vetroresina). This is substantially unique: Ferrari chose fibreglass for weight saving and flexible production. The Vetroresina specification was replaced in 1977 by steel bodywork due to production problems with fibreglass (cracking and fit problems). For collectors the Vetroresina specification is substantially scarcer and generally higher priced than the steel specifications. Confirmation via factory chassis number and Ferrari Classiche essential.
The 308 GTB production is divided into four production Tipos: - Vetroresina (1975-1977, around 712 cars, fibreglass bodywork, Weber carburettors, 255 hp) - Steel bodywork (1977-1980, Weber carburettors, 255 hp) - 308 GTB/GTS i (1980-1982, Bosch K-Jetronic injection, 214 hp EU / 205 hp US due to emission standards) - 308 GTB/GTS Quattrovalvole (1982-1985, four-valve head, 240 hp EU / 230 hp US) For collectors the Quattrovalvole is generally the most power-oriented 308; Vetroresina is the most scarce; carburettor specification is more classic.
In 1977 Ferrari introduced the 308 GTS - targa specification with removable roof panel. The package includes identical V8 drivetrain as the 308 GTB Coupé but with removable roof panel (can be manually placed or removed, with storage in the boot). The 308 GTS has reinforced chassis structure for open-body torsion stiffness. For collectors the 308 GTS is popular due to open driving experience and Magnum P.I. connotation; 308 GTB is generally higher priced due to pure Coupé specification and scarcity.
The 308 GTB has seen a substantially stable to rising appreciation curve since 2015. Well-documented 308 GTB examples in original specification with proven service history sit in a strong segment for classic Ferraris. Vetroresina examples (scarce early production), Quattrovalvole (power-oriented), and non-red 308 specifications are substantially higher priced. For sellers this means a well-documented 308 GTB with proven service history at Ferrari Classiche or recognised classic Ferrari specialist, original original specification, and Ferrari Classiche certification attracts strong international interest.
308 GTB Coupé (1975-1985) or 308 GTS Spider (1977-1985, targa specification with removable roof panel). Additionally production Tipos: Vetroresina (fibreglass bodywork, 1975-1977, around 712 cars, substantially scarce), steel bodywork (1977-1980, Weber carburettors), 308 GTB/GTS i (1980-1982, Bosch K-Jetronic injection), and 308 GTB/GTS Quattrovalvole (1982-1985, four-valve head).
The 308 GTB is available in classic Ferrari colours: Rosso Corsa (signature 308 colour, around 60% of production), Giallo Fly, Bianco Polo, Azzurro Hyperion, Nero Daytona, Verde Medio, Marrone Colorado. For collectors non-red 308 specifications are substantially value-adding.
The F106 AB V8 (naturally aspirated, 3.0 litres, 240-255 hp depending on specification) is Ferrari's first regular production V8. The engine is mounted transversely in mid-rear position (identical to Dino 246 specification). For collectors, F106 condition, timing belt status (replaced every 30,000-50,000 km), oil consumption status, and valve condition are essential.
For collectors production Tipos are substantially value-driving. Vetroresina (1975-1977, around 712 cars, fibreglass bodywork) is the scarcest; Quattrovalvole (1982-1985, four-valve head with 240-255 hp) is the most power-oriented; carburettor specification (1977-1980) is generally more classic than injection specification (1980-1982). Confirmation via factory chassis number and Ferrari Classiche essential.
The 308 GTB has original 14-inch Cromodora wheels (classic star-design wheels). For collectors original Cromodora wheels (not replaced by aftermarket) and factory original interior (Connolly leather, wood trim, classic dashboard elements) are essential.
Ferrari Classiche-recognised service is essential for classic Ferraris. For 308 GTB: F106 V8 service (timing belt replacement every 30,000-50,000 km, valve clearance, oil consumption status), manual transmission service, fuel system (Weber carburettors or Bosch K-Jetronic injection), electrical system condition, and historic service documentation.
For 308 GTB collectors well-documented low-to-moderate mileage (under 100,000 for regular model years, under 50,000 for low-mileage examples) with full service history is more attractive. Number of previous owners, market version, and geographic distribution are value-adding.
Note: These factors may influence buyer interest. Value depends on many factors.
308 GTB Coupé (1975-1985) or 308 GTS Spider (1977-1985). Production Tipo: Vetroresina (1975-1977), steel carburettor (1977-1980), steel injection (1980-1982), or Quattrovalvole (1982-1985). Model year, chassis number, engine number, and market version.
For 308 GTB Ferrari Classiche certification is substantially value-adding, particularly for Vetroresina specification and non-red specifications. Apply via Ferrari Maranello via Ferrari Classiche form. Confirms factory chassis number, factory engine number, production date, production Tipo, and 308-specific specification.
All invoices from Ferrari Classiche or recognised classic Ferrari specialist. For 308 GTB: F106 V8 service (timing belt replacement every 30,000-50,000 km, valve clearance, oil consumption status), manual transmission service, fuel system (Weber carburettors or Bosch K-Jetronic), electrical system condition, and historic service documentation.
The F106 AB V8 (3.0 litres, 240-255 hp depending on specification) has known points of attention: timing belt replacement every 30,000-50,000 km (essential to prevent engine destruction), valve clearance (annual adjustment), oil consumption status, Weber carburettors or Bosch K-Jetronic injection service.
The 308 GTB is available only with manual five-speed gearbox. Document transmission condition, clutch status, limited-slip differential service, and rear axle condition. For collectors proof of original transmission is essential.
Paint colour with Ferrari factory code: Rosso Corsa, Giallo Fly, Bianco Polo, Azzurro Hyperion, Nero Daytona, Verde Medio, or Marrone Colorado. For collectors non-red specifications are substantially value-adding. Document rust status (classic 308s have rust points of attention on door panels, wheel arches, and floor).
Number of previous owners, mileage, market version, model year (1975-1985), production Tipo, and Ferrari event participation. For collectors: low mileage (under 100,000 for regular, under 50,000 for low-mileage examples) is substantially value-driving.
