ask your LHS... what kind of car he has good support.
all those 3 cars listed by u are good... not GOOD... but GREAT cars...
you dont want to buy a car that is very hard to get PARTS and you have to wait 2-4 weeks just bacuase you dont have the DOGBONE!!!!
either way.... you will win in RACES if you get used to the car you love.
just sharing info:
SHORT TIGHT TRACK... go for SHAFT driven car.
LONG BIG TRACK.... go for BELT driven car.
