Iriz FL of course!

MyVi lacks the refinement and definitely looks and feels cheap on the inside, though the top spec does have good safety features...

Better go test drive both on the same day...you'll then know which to go for..

Did you over-revved the Iriz? Just give it enough where the rpm is at 2k, any more is basically wasted petrol...

Also, was it the latest Iriz FL you tested?

Great comparo...just to comment on the few items;

Powertrain/Driving/FC
- CVT smoothness has improved much on the Iriz FL, there's little to no lag from standstill
- Better ride/handling & comfort on the Iriz FL
- Stability & faster acceleration especially when you floor the Iriz FL, you can feel the pull
- NVH has greatly improved, way better than the new MyVi

Misc
- After sales support is still a huge problem for Proton. CoSE is not any better, while even though the 3/4Ss are better in Customer Service they keep promoting more expensive parts from their own suppliers than that of Proton (normally quotes no stock).

Now we'll see how Perodua responds (depending on the sales figures of the Iriz) when they release the new MyVI FL.

Most if not all of your worries like low quality workmanship during servicing and the overall build quality of their cars like their punch gb have been addressed since the company became BaoTeng. The issues with available part stocks, normally only on those before Wira time or for the imported X70. I've owned the Gen2 for 10 years and have never had problems with parts (but Proton Parts Centre is accessible to me, so maybe it's a factor).

There's a lot to improve in terms of after sales on Proton's part. Mainly the attitude and the long wait/efficiency/dedication.

Since you've been a loyal Perodua customer for some time, I believe you already build that relationship with the SC you're visiting. The MyVi looks like a more satisfying overall ownership experience for you.

Though the iRiz FL appears to be a more matured & refined car compared to the MyVi, but the MyVi should be good enough to satisfy your needs and maybe even impress you since you're coming from the Kancil.
