Vehicle Identification
- Serial Number Prefix Letter Code |
| The engine number
prefix comprises a series of letters and numbers, presenting in
code the cupic capacity, make, the ancillaries fitted, the type
of compression. |
|
The car number
prefix comprises a series of letters and numbers presenting in code
the make, engine type, body type and the series. |
1st Prefix
Group - Cubic Capacity, make and type
1st
Prefix Number: 18 = 1800cc
1st
Prefix Letter: G = MG or V = Vertical (in-line) |
|
1st Prefix
Letter = Name
G = MG |
2nd Prefix
Letter = Engine Type
H |
3rd Prefix
Letter = Body Type
N = 2-seater Tourer
D = Coupé or GT |
2nd Prefix
Group = Gearbox and Ancillaries
Letter
U = Centre gear change
R = Overdrive
