Besides after heavy rain, is the kurk kurk sound noticeable during normal drive or going over bump ?
How loud is the sound ?

600km per tank!?
Mostly highways ?

I can only.achieve about 530-550 per tank for pure city driving

Booked meteor grey for my relative since early last month. Called SA today and told me the latest batch of meteor grey got paint defect so all have to redo. Don't know if this is an excuse or not but looks like they are expecting me to wait for total of 3 months. Might as well change order to CX3 since its supposed to arrive next month.

Based on other comments here, I went for test drive in the Volkswagen Jetta. Surprisingly the engine is blazing fast! Handling is very good too as I could do high speed turns with tyre squeals and still in control. Only problem is the interior looks a bit cheap especially the centre console. That and also almost at the end of the test drive, the gearbox suddenly jerked loudly with the whole car shaking. That kind of reminded me of the horrible DSG episode. Sigh...there is no perfect car.

What are the complaints about?

I've been using Shell oil for the past 5 service.
