I bought persona sv in 2014 as well, but auto. Currently mileage near to 90k.
I dont have problem you have mentioned.
My fuel consumption is around 7.8 litre/100km

First time owner of Persona so have no experience with B-line or whatever line. Honestly, I don't even know what line mine is. LOL!

Mine is all-round discs. So far, feel braking is adequate. Certainly better than my previous Saga LMST which had rear drums.

i can answer the bold part..i change my persona silicon steering rack bush 2 weeks ago..basically when ur steering feels misaligned even after alignment, just check for these bush..the old bush have cracked, hardened & didn't have much grip to the steering rack..i pay rm120 for the bush (pair) & labour service..

Don't forget bout the bulb you need to buy for this headlamp. And normal bulb would not be bright in projector headlamp.

seems normal price to me.. If its Eagle Eye or Depo brand then surely can tahan.

Water pump, foreman suggest to change after 150-200k km mileage.

If u don't change it as a preventive maintenence, when shit happens, it leaks or worst the fin breaks and water cant pump, then be prepared for a major overhaul. Can be a life or dead situation when ur engine seize while driving at high speed.

if can modify like this it will be good

Btw just to share with u all.. I went shopping for some parts on Lazada.. Combined with some discount codes and managed to get some really good deals all for around RM2k.
Basically bringing back my nearly 7 years 10 months old car back new. 

Would recommend e-shops in Lazada such as SM Auto, Vanli, The Spare Parts Shop etc.. Good and secure packing with bubble wraps and very quick delivery. Orders all were processed and shipped within 2 days.

Can get Hankook V12 Evo 2. Very good tires and cheap too. It's ultra high performance category. Mine I got cheapest is Rm270/pcs 205/55R16

I know XM2 last damn long but has uneven wear issues the last time I used it. Its an energy saving tire so I dont expect much performance out of it anyways.

Hankook V12 Evo2 is much quieter than the evo1, Grip level not sure as tires were brand new (<100km) when i went up genting last sat and it was skidding quite a bit. It was raining otw up so Im not blaming the tire. Personal experience the V12 evo1 grip level were on par with PS3 and T1R.

Toyo T1R threadwear 240 (or 220 forgot ady) lasted 19k km, PS3 threadwear 280 lasted 28k km, V12 evo1 threadwear 320/340 lasted 33k km.
V12 Evo1 was kinda hard wall and medium compound hence it was noisier than PS3 medium wall, soft compound.. PS4 threadwear 320 but it's way noisier than PS3, but grip level is god like.

I change 3rd times already, 7 years car.... 

May I know what Engine oil you use? 30 or 40?

Nope, is just my own survey. I suspect cloud it be I use the 30 EO that's why the gasket won't last long!

Cos when new car the 1st few years was using 40, and the gasket can last about 3~4 years, which is reasonable for me.

Is just I guess only, due to 40 can take higher temperature, I check with workshop, mostly say not related....

I’m using Tesco fully synthetic nowadays. Quiet engine and very responsive. 10k km still run smoothly.

I usually request the fluid to be filled to the half between min and Max level. So far looking healthy. Don't think you should bother.
