Can you explain the RA codes please?
These are Department of Transport codes for the vehicle model categories as perceived by them and not, in some cases, corresponding to what we would have set up. As a consequence they make no distinction between coupe and 2+2 280ZX and there are no categories for coupe Z31 or coupe Z32 or Z32 NA of any description...
R2009 = 240Z
R2034 = 260Z
R2035 = 260Z 2+2
R2113 = 280ZX (I assume '79/'81 series manual)
R2114 = 280ZX auto ('79/'81 series)
RA035 = 280ZX 2+2 targa (you might see another problem here - do these include the early targa or only the '81/'83 series?)
RA036 = 280ZX 2+2 targa auto (as above)
Z31 - see previous post
RA183 = 300ZX turbo (Z32 models)
RA184 = 300ZX turbo auto (Z32 models)
RA384 = 350Z
Code for 370Z unknown at this point in time...
You can see that the categories (which were based around UK cars) now throw the data into confusion with the influx of import variants and the non-recognition of the 280ZX coupe, even though it was an official UK model '79 to '81.
You can see why DVLA mistakes creep into registration documents.
