Opel Owners Club of SA

Hey guys I'm looking for feedback from owners. I'm looking at purchasing a new 1.7dti sport. Trading in my Astra H , need a bakkie for work .
Whats the fuel range for city driving and open road driving. I still have to go for a test drive in one. How is the ride in these bakkies compared to a avg car.

What does the services cost minor and major? Would love something with better performance like the 1.8, but since it wont be close to my 's performance
i might as well go for good fuel consumption and lousy performance. So guys any feedback will be appreciated.

thanks!
