So I switch to 530i, this time a saloon.....and give it a try. May be it was the M-package carrying 18" heavy wheel. Actually, I feel that a Toyota Mark X 250G feel a lot more powerful than my previous Wagon.
What is sprint booster?, what does it do, first thing I need to sort out is radio. Because it's grey import car so radio is not right. Then performance, fuel saving and more torque, may be lower the car a bit.
Sprint booster is a device that helps cut out any lag due to the wire by throttle.... makes throttle respond better!
