Waitlists are fairly meaningless marketing claims all mfrs use to create aura of scarcity/desirability among clueless potential buyers/casual observers....

US mkt prob buys 50-60% of world's $150K+ cars....and, in US, deposits on cars are trivial (perhaps $1-2K and fully refundable; most repeat custs at F/MB/P dealers actually are asked for no cash deposit and are simply offered early slots on any car of interest)...so waitlists/deposits mean nothing in major US mkts...

That said, given the slowing economy in the finance industry-dpdt NYC and London mkts (and their purchs of sports/GT cars in various wkend home mkts like FL, MC, CA, etc)....and falling home prices in CA....suspect global "waitlists" for $150K+ cars are more phantom-like than usual....

Many emerging mkts still struggle w/basic roads, high-octane fuel, and personal security issues vs driving high-end cars in their own regions....so many Chindia/Russ/Mideast buyers obtain and keep their more interesting cars in the Lond/Swiss/MC/LA/FL mkts where they have wkend houses.....so difficult for mfrs to easily reallocate such cars to arbitrage FX diffces
