I'm posting the following reply here as it is a more appropriate forum than Jag Lovers where there are many non North American listers. This thread started with a suggestion that XJ40s should be in a separate class than X300/X308.
a few numbers... currently, in the JCNA standings there are
Champion classes :
29 E-types, most 6 cyl
13 XJS, oldest one being 1987.
zero XK150s
5 XK120
2 XK140
10 XJ6 ( 2 XJ6 I 2 XJ6 II 6 XJ6 III )
5 XJ40/X300
It's pretty similar in Driven with :
16 E-types
8 XJS
1 XK 120
7 XJ6 ( all series )
3 XJ40/X300
Those standings ( updated last night btw ) currently include all entrants with at least 2 shows. 28 events included (6 still missing) so it is a fairly representative sampling.
The lack of early XJS is either a sign that they don't enter knowing they don't stand a chance, or they are too few around. Doesn't seem to me that splitting the class would accomplish much. On the other grouping the XKs, which will probably be a very unpopular proposal, would make sense.
