Nitrogen cost RM20 for 4 tyres. Free subsequent refill. I pump nitrogen at tyres shop in Taman Maju Jaya. Not 100% nitrogen. Only 91 kpa on nitrogen machine. The rest is is oxygen. Tyres pressure stay the same until 3 months. I noticed less bouncing compare to 100% oxygen.

For the budget, you should go for PS3. Grip and comfort in 1 package. XM2, Cdrive2 and CC5 cannot even offer 2/3 of the PS3's grip.

Just sharing. My 9 years old ride has the unpleasant air cond smell too. Even more in fan mode. Send for major service but it only remain no smell for few months.
DIY open up the glove compartment, spray the air cond cleaner to the condensor and cooling coil, close and let the air cond run for 20 minutes and bingo.
The unpleasant smell does come back after few month so the cleaning need to be done again.

Don't remember the brand but its green can bought from Carrefour. Rm19 only.
Need to open up the glove compartment on front passenger side, after that, there is another panel need to take out and you will see
the cooling coil. I just spray all over the cooling coil. The cleaner dissolved the dirt and channel out to the air-cond hose. Need to turn on the
air-cond until the water come out is clear.
Picture only available on next DIY.

Use philips screw driver and 10/12 spanner. and need to unscrew the mini hydraulic mounting as in my other ride.
