a lot of people complain about ECON button on. So i just turn on econ when reach to traffic jam. After traffic is clear and i need more power, then i will turn off. Conclusion , seldom use ECON mode. I found my car no power when ECON is on and need to press more harder.
When normal traffic, no need to use ECON button.
My friend use ECON mode for 2 month, then he decided dont want to use as it is not fuel saving. Don't use is more fuel saving.

My wife finally got her car after 3 wks (V spec) Metallic steel. But she found it quite hard to "anticipate" the front part while parking.
So I was thinking to install front sensor for her, to avoid her knocking into stuff. Anybody can recommend where to do it and roughly how much it will cost?
