A Quick History and Recent Buzz:

Debuting in 1966 as the "Duetto" to celebrate Alfa Romeo's centennial, the Spider evolved through various updates to keep up with changing emissions regulations and consumer preferences.

 

The 1973 Series 2 version brought a sharper front end, enhanced rust protection, and U.S.-spec fuel injection, making it both compliant and a fun roadster to drive.

 

Recently, a pristine 1973 model sold for $59,995 at a private sale in Australia, underscoring the demand for low-mileage examples. Additionally, Hagerty's valuation tools have noted auction highs reaching $40,308 over the last three years, with 43 active listings on platforms like Classic.com as of mid-2025.

 

Enthusiast forums are buzzing with restoration tales, including a viral YouTube review from Trade Classics that raves about its "stunning red exterior" and track-ready performance.

 

Key Specifications and Features:

The 1973 Alfa Romeo Spider was mainly available in the 2.0-liter Veloce trim for the U.S. market, focusing on balance rather than sheer power. Here’s a closer look:

 

• Engine and Performance: Under the hood, you'll find a lively twin-cam inline-four engine with a displacement of 1962 cc (or 2.0 liters) that cranks out 129 horsepower at 5,800 RPM and 130 lb-ft of torque at 3,700 RPM. Thanks to the Bosch electronic injection system (the Spica setup for U.S. models), starting is a breeze, and the power delivery is smooth as silk. This combination helps the 2,292-pound roadster sprint from 0 to 60 mph in roughly 10 seconds, reaching a top speed of 118 mph (190 km/h). Owners often rave about the engine's "energetic pull to redline," although some do mention a quirky trait: it tends to consume oil at about a quart every 500 miles.

 

• Transmission and Drivetrain: The car comes with a standard five-speed manual transmission, paired with rear-wheel drive and an optional limited-slip differential. With disc brakes on all four wheels, stopping power is impressive, a real standout feature for cars of this era. 

 

• Mileage and Fuel Economy: According to real-world data from owners, the average fuel economy sits at around 10.01 MPG combined, based on 8,547 miles from tracked vehicles. In the city, you can expect around 18 MPG (12.6 L/100 km), while highway driving can yield about 24 MPG under ideal conditions. While that might seem thirsty by today’s standards, it’s pretty typical for sports cars from the 1970s. You can anticipate getting about 300-400 miles on a full tank, thanks to its 14.5-gallon fuel cell.

 

• Features and Value Additions: The fabric convertible top folds away neatly, and there's an optional hardtop for those who want to enjoy all-season driving. Inside, you’ll find leather bucket seats, a wood-rimmed steering wheel, and a straightforward analog gauge cluster. While rust-prone sills and floors can be a common issue, well-restored models often feature upgraded suspension (like Koni shocks) and modern audio systems, which can boost resale value by 20-30%. Safety features are pretty basic, just lap belts and no airbags, but the car’s low center of gravity really helps with handling. 

 

Market Value Factors and Comparisons:

Valuation hinges on condition, originality, and provenance. Fair-condition drivers start at $5,695, while concours-level gems exceed $60,000.

 

Average sale price sits around $17,118, per Auto Trader data, with Hagerty #3 (Good) condition pegged at $12,000-$15,000 in the UK equivalent (£12,704). Low-mileage (under 50,000) cars with matching numbers command premiums, especially in red or black. 

 

Compared to Peers:

1. Vs. Fiat 124 Sport Spider (1966-1985): The Fiat, a mechanical twin built on a shared platform, is cheaper ($8,000-$20,000) and more reliable daily, but lacks the Alfa's prestige and sharper handling. Alfas hold 20-50% higher values due to brand allure. 
2. Vs. Triumph TR6 (1969-1976): The TR6's 2.5-liter inline-six (104 hp) offers similar fun at $10,000-$25,000, but rusts faster and feels less refined. The Alfa edges out in elegance and cornering.
3. Vs. MGB (1962-1980): Ubiquitous and affordable ($5,000-$15,000), the MGB is easier to maintain but underperforms the Alfa's twin-cam zip. 
4. Vs. Porsche 911 (Early 1970s): A league apart at $80,000+, the 911 trumps in performance but dwarfs the Alfa's approachable charm and sub-$20,000 entry.

 

Restoration costs ($10,000-$30,000) can boost value, but authenticity rules; modified "sleepers" sell for less.
