Montecristo Minis are great quick drive smokes.

For your 30 minute drive, I would recommend several PC/smaller sized smokes:

MC #5
Tatuaje Havana 6 Angeles
Plasencia TKO (and it's Famous Smokes eqivalent)
CAO Brazilia Gol
The little Partagas Black (I think the Pronto?)
Onyx Reserve Mini Belicoso
PAM #35
AF Short Story


and the list could go on....
