No aux jack for 408, only USB.

I think your statement saying that 408NA will easier get sick compared to turbo is not entirely true. Mine is first batch 408NA and so far the only major issue faced (touch wood!) was crack on petrol tank, which is believed due to manufacturing defect and got nothing to do with it being NA or turbo.

And for information, they've replaced my battery to DELKOR during my 20k service. At first, the service advisor said that they will not replace it unless if the test indicate battery replacement is required. When collecting my car, I noticed that battery replacement was part of the list and they even indicate the brand of battery they've replaced with.

However, they still didn't managed to rectify the rattling issues Anyone did manage to rectify the rattling issue?

Mine is 2.0. Handling is impressive, though I believe it's turbo sibling does better in this department. However, 408T has far more precise steering due to its electro-hydraulic steering, and this will results in higher confidence when doing high speed cornering.

If your choice does really comes down to how the car handles, I suggest you to do few more test drive before making your decision. I've tested both variants, 408T at Seremban and 408NA at Glenmarie, both location have 'good' routes to test the car's handling.
