I have used BMW 5 Series 535i for about 2 years and have been thoroughly satisfied with its classic sedan look and performance. This car not only looks classy and suave but also performs in a similar pattern. With brake energy regeneration charges the battery when brakes are applied. Furthermore, supreme engine performance and eight speed automatic transmission system ensures a smooth drive quality. The entertainment and communication unit is one of my favourite aspects about the car. The entertainment unit has a iDrive controller and display, TV function, rear seat 2 tilt-able 8 inch screen. BMW has given great deal of attention to passenger safety and security. Among standard features, 5 series 535i has Dynamic Stability Control (DSC), Anti-lock Braking System (ABS), traction mode and braking assistance. Inside the car, there are driver and passengers air bags with side air bag, front and rear head air bags. Park Distance Control (PDC), a handy feature, assist in front and rear parking with visual and audio feedback. Moreover, the Condition Based Service(CBS) helps with keeping track of fluid levels and depreciation of every single components. Whenever there is a requirement of service this system will inform with the help of info display in the cockpit.
