I like how BMW NA forces you to order leather for $900.

On the BMW USA website:

Coupe: Alpin White, Silver Novillo lthr, EDC, aluminium trim. Total: $58,950
Sedan: Interlagos Blue, Black Novillo lthr, EDC, aluminium trim, split folding rear seats, electric moonroof. Total: $58,250

On the BMW UK site (German-spec M3s have too many options and I can't understand them all )

Coupe: Same colors & trim, Premium sound, Comfort Access, Shadowline trim, Climate comfort windscreen, sliding front armrest, adaptive headlamps, high-beam assistant, EDC, front & rear PDC. Sat nav is standard on UK models. 54.620 GBP. I didn't order cupholders because I don't want folks drinking and spilling their drinks while I

Sedan: Same options as above, plus split-folding rear seats, and trunk storage tray. 54,450 GBP.

Edit: Interesting tidbit. On the German BMW build-your-own, I think DCT is offered as an option.........
