JudasIscariot: I ride either a MANN or Solaris bus. I will NOT buy or drive a car here in Warsaw. People drive like crazy here and the upkeep, taxes, insurance payments, and the amount of suspension work I would have to do on my car (you know because of our famous roads "Jechalem sobie dziura a tu nagle prosta droga!" quote from Nonsensopedia :D ) is too goddamn much.
Riding the bus also affords me time to play on my PSP and not give a damn about having to drive. So liberating!
Oh, Solaris Urbino and Man's City Lion are pretty awesome. But they usually come in the "przegubowiec" form, so they do well on wide roads but don't do so well on twisty-hilly suburbia, which is where i live. Word of warning, riding buses lead me to my "if i can't get there with a bus that goes through my neighbourhood, then it's FAR AWAY" mentality.
And, if buses interest You,
check this out. Never knew there were so many types.
