Hi KKP, welcome to AL forum. I had experience with Mazda BHALP. But some of my friends are using 323. Chami (mazdaspeed), pls comment on this.
Some issues on FB 15 and Lancer, there is a problem in the air flow sensor in FB15 and spare parts are very high prices in Lancer models. Guys, pls correct me if i am wrong.

I think comparing Fuel economy, Spare parts & maintaining cost, Mazda 323 is good for your requirement. Good Luck.
