Even though an S600 Pullman exists in BD......I would still say ppl will dig other limos.......like the towncar, deville, hummer, escalade etc etc....the reason is, S600 Pullman's interior is more like a business interior..I mean its more like for ppl who are prominent businessman, and always keeping busy with business related stuff, that they are always short of time.....so they need to do business even when they are in the car......and S600 Pullman, Arnage Mulliner Limo, Maybach 62 is the appropriate vehicle for them......and these vehicles can only accomodate 2-4 people (excluding the driver and the front passenger)
On the other hand, towncar, deville, escalade, hummer etc etc can be used as a business vehicle as well as a party vehicle. these cars can accomodate way more ppl than the S600 Pullman, Arnage Mulliner, Maybach 62.......so if u plan to use ur limousine to cruise around the town with friends and family and party in it, then its better to go for towncar, hummer etc etc limos.
for example, here are the interior differences.....
Pullman, Mulliner, Maybach interiors
Pullman

Arnage Mulliner stretch
Maybach 62
Towncar, Deville, H2, Escalade, Excursion
Towncar

Deville
H2
Escalade
Excursion
So there u go......ppl who need a business limo, where they and their business partner(s) r going to ride all the time, and don't need much of an accomodation, then they'll go with Pullman and alikes...........and ppl who want to accomodate more ppl and cruise around the town with friends and family, they'll go with towncar, hummer and alikes. (the stretch excursion can accomodate 22 ppl. don't know abt the others)

P.S........the interiors of the towncar, deville, h2, escalade and excursion limos are not necessarily exact for every one of them........u can choose ur own interior design.
