Advice on 08 93 convertible 1.8t please

[CarlG77]

Hi

I am thinking of getting a 08 plate 93 convertible, with the 1.8t engine and vector spec plus sat nav and full blue tooth connectivity and would like some advice and comments from existing owners

I really like the car but have a few concerns that are stopping me actually doing it
- Reliability: things like the JD Power survey dont rank them very well
- Build quaility: as above.
- MPG: I can't find any real life figures, but people generallly say the SAAB turbo engines are thirsty

I have a 03 plate celica at the moment that is still running perfectly which is why the relaiblity concerns me.

I am also curious about the Sat Nav / entertainment system:
- when it is only showing the radio station / cd info is the display in colour ?
- does the blue tooth intergration work well and is the use of the wheel controls to use the phone easy and quick enough ?

Thanks in advance for any comments and advice
