I've a subscription of the 'Absolute Lotus' magazine and it was a pleasant surprise when the latest issue arrived with the Europa cover story. Five variants of the Europa are presented (S1, S2, S2 Else, Twin Cam and TC Special) and compared to each other. Worthy winner is the S2 followed by S1, TC, TCS and S2 Else.
I think it is well written and a nice read. I stumbled across the same issue concerning the wart indicators being introduced during S1 but I though the author may have confused it with the Lucas tail lights being introduced with the S1B.
For me as an S1 addicted Europa owner it's good to see that the S1 receives the recognition it deserves in my eyes. The whole editorial discusses the interior and bulkhead design of the S1. Another surprise are the given values where the S1 is listed as the most expensive one:
S1 35,000 GBP
S2 22,000 GBP
Twin Cam 27,000 GBP
TC Special 30,000 GBP
I'm not sure if these are realistic values but at least it reflects the fact that the early Europas are the more collectable ones.
