Found some flowers (not sure what to do with them except beat people with em) and a classic car next to a car wash. It had pimping missions. After finishing em now hookers pay you to have sex with them.
I also jazzed up my low-rider at the car shop. New hydraulics, wheels, exhaust, paint job (one I picked looks like the Diablo Stallion in GTA3), new interior and chrome siding. Pretty cool stuff. There should be other car shops later on but this one only lets you bring in low-riders. I swam accross to the other city and the cops got pissed cause I wasn't supposed to leave and gave me a 4 star rating just for getting to the other side. Cool that you can get over there still but like in the others, they want you to work on one city at a time to start out.
I'm at 10.70% complete only but have been exploring like hell. This game is so massive.
