I used to drift with Mini-Z AWD. It is pretty hard compare to bigger size ones, but I can drift around indoor. Office, living room, my room, etc.
Also, when you get better with small ones, it is way easier to drift with bigger ones.

 

kyosho fw series, preferably the touring fw-06. great drifter, i run circles around all my friends hpi's

 

no offense but HPI car's are kinda lame...and I know from experieince... they do make some nice stuff like the savage but they're cars are eh....the most serious drift car's are yokomo http://www.yokomousa.com/

 

Meh there's fanbois for every brand out there.

 

Yokomo's the way to go if u into drifting. best parts, bodies, wheels and tires out of all.
