pun intended , i have the same lumbars as any other human :_
the new civic is extremely uncomfortable , the seats are all but hard on your back and the drive is worse than corolla. it just feels so twitchy and not planted . you spend 3 million on this atlas crap and there is nothing in the name of refinement. i know i can be JDM biased but over the course of last years, the successive new models of local hondas and corollas have not offered any material comfort upgrades . infact, got worse.
anyone who has owned a good clean JDM or a german car will easily tell the difference
parts are easily available for JDM . the only issue is when you break a light or have a side mirror mugged. i got a replacement windscreen for mira 2008 easily for 8000 ( installation included ) . consumables like air, oil filter etc are all available and cheap. the same disc pads for xli can be used for premio, prius.
as for the O2 sensor, it is expensive, but you dont have to change it unless the engine diagnostic light comes up. Xulfiqar can beter guide here. o2 sensors for local cars arent cheap either, swift o2 sensor is around 17000 rs
