Queries on SX4 ZXi Model. Review on Maruti Suzuki SX4

One of my friends having expertise in automobile has suggested me the following cons of SX4. I have driven ZXi model around 300KM in city condition and am specially concerned about fuel consumption.

1. Electronic Power Steering may be difficult to handle on high speed if the fuse is blown and he told power assisted steerings of aveo is a better option.

   
   




2. Even with a ground clerance of 19cm, the lowermost part subject to friction on himalayan humps on Indian Roads is the Petrol Tank causing safety concern.

   
   




3. Drags are more on 205/60 R16 tyres resulting in a lower mileage.

   
   




4. The interior plastics are really cheap and do not gel well with a C segment car of this price.

   
   




5. The Mileage observed after 300km on city driving is 8kmpl on high octane fuel.....is it likely to increase after servicing?

   
   

I invite the user views on the above observations.

Thx
