Roadster market over all brands is small, factor in the price point of a Z4 and it drops off even more. Yes its a great looking car but its overpriced for what it is, which turns away buyers.

Base prices

z435is - 64k
335is vert - 60k
135is vert - 47k

E550 Cabrio -66k
SLK55 AMG - 67.9k

S5 Cab -60k
TTRS - 58.9k

Cayman S - 63k
Boxster S - 62k

Point is you will cross shop many of these, some have 2 some have 4 seats but all are verts in the rough same ballpark (sans ttrs/cayman,)

With THAT much competition its no wonder why you dont see many Z4s. Also a sure sign of being overpriced is the 1-2 year depreciation. The sticker on my 35iS was 10'9k USD i picked it up for 56k USD. Almost 50% loss in 16 months with only 14,000 miles on the clock. The steep buy in for 1st time buyer makes the already rare roadsters even more and in turn makes the 2nd hand market very small. It would sell much better if the 35iS was adjusted down 55k base.
