i have sold my city 98 and bought 2002 city auto. i have an option to go for imported cars also like passo 1000 cc, mira 660 cc but the main issue was the parts and thats all. we have to arrange it now from japan or dubai. i am sure in future these parts will be availble but i think it will take quite time. No doubt imported car drive pleasure was way better then locals, but in my thinking parts are main problem. Vitz 2005 onwards u cant instal CNG in it but its very comfortable, resale is low.
Best of luck.
