Hey!
Australian culture grew up on tuff RWD cars, so we have a myrad of nice RWD vehicles that are more than capable of doing donuts!!
You do realise that Ireland isnt the only country that does them!
Im sure you will be pleasantly surprised at the Australian car scene.
Just avoid states that have anti-hoon laws implaced, as they will heavily fine and impound your car if your caught multiple times doing such things that you stated.
Anyways im guessing you like your smaller RWD cars, import RWD tubos like s13's are around the low to mid teens, r32's and r33 GTST's are anything from $10K to $18K
Toyota dont really offer anything interesting here locally, but the localy made vehicles (Ford/Holden), you can pick up a highly modified v8, v6 or 6cyl turbo for under $12K which will do more than rip circle work.
