We don't quote prices here — the market moves, and a figure would be out of date before long. What doesn't change is what drives value, and understanding that helps you judge whether a car is fairly priced.
Condition and structure first
Because rust is the model's great enemy, a genuinely sound, structurally honest car commands a real premium over one that's rotten or full of filler — even if the rusty car looks smart. A documented, high-quality restoration or a well-preserved original is worth paying for; a cheap car with hidden structural rust rarely is.
Veloce over Normale
The Veloce — twin Webers, the bonnet scoop, around 112 bhp — was built in smaller numbers and is faster and more sought-after, so it commands a clear premium over the single-carburettor Normale.
Originality and matching numbers
Cars that are original or matching-numbers, in their correct colour, are valued above modified or cobbled-together examples. That said, a sympathetically fitted larger engine (like a period 1750) can make a car more usable — it just isn't matching-numbers, and the price should reflect that.
Rarity and history
Right-hand-drive UK cars are rarer than left-hand-drive, and documented history — especially factory confirmation from the Alfa Romeo Historic Archive — adds real confidence and value. See Identity: chassis numbers, 101 vs 105 and RHD rarity.
The sensible approach
Buy the best, soundest car you can afford, prioritise structure and honesty over shine, and let condition and provenance guide you. For current values, the owners' club, the classic-car price guides and recent auction results are your best gauge.
