Bernard,
At the current exchange rates (1.3 US$/GBP and 101 Yen/$) 758,000Y for the SL is 10% more expensive than the UK cost NEW(£5,300, £4,400 excluding tax)! So I'm not too surprised that they're not 'flying off the shelves'. In today's market even mint, out-of-box Leicas aren't part-exchanged by dealers for more than 50-55% of the cost new. Cash buy-in would be even less. The 20% discount on the new px makes them expensive, both in absolute and relative terms, IMO.
Thanks for the info.
Best,
M
