History & Identification

Identity: Chassis Numbers, 101 vs 105 and RHD Rarity

BeginnerMaking sense of Giulia Spider identity — the Normale and Veloce type numbers, why matching numbers matter, the 101-versus-105 interchange, and why right-hand-drive cars are rare.

Knowing what a Giulia Spider *is* — down to its type number — protects you when buying and matters for value. Here is the essential framework.

The type numbers

The 101-series Giulia Spider carries different type designations by version and steering:

  • Normale — 101.23 (left-hand drive) / 101.19 (right-hand drive, *guida a destra*)
  • Veloce — 101.18

Check the chassis and engine numbers against the type the car is described as. It is a quick, revealing sanity check.

Matching numbers and the 101/105 interchange

Because 101-series and later 105-series parts interchange freely, a "101" car can carry later components or a later engine without it being obvious. For originality and value, confirm the engine is the right type and, ideally, that the numbers match the car and its paperwork. A mismatched car isn't necessarily a poor buy — but it should be priced and described honestly as one.

Why right-hand-drive cars are rare

The Giulia Spider was built overwhelmingly in left-hand drive. Right-hand-drive *guida a destra* cars were made in far smaller numbers, so a genuine RHD car — particularly a UK-market one — is comparatively uncommon. That rarity, matching numbers and documented history all add to a car's standing.

Normale or Veloce for value

The Veloce (twin Webers, the raised bonnet scoop) is faster, rarer and commands a premium over the single-carburettor Normale. Confirm which you are looking at both by its type number and its features — the two are covered in the companion article on telling them apart.
