I drive a d15b mt eg sedan and I fell in love with it as well, to the point of giving it a name and treating it like a girlfriend

I once thought of swapping it to a Super Touring and a 4AGE silvertop ae92. Dati yun. Pero I held on to it upon realising how great and practical a car it is.

With your 100k and the matic ESI, I'd up for the d15b swap and suspension/tire upgrades. Pag may natira, up the brakes as well, yung pang SiR.

Swak sa budget yun. Ok naman ang d15b eh, tipid sa gas pero hindi katitipirin sa power. Kahit VTI-S kaya nitong sabayan even on stock
