SAAB 9000 Tech Questions

Hi Folks, well We didn't get a 93 or a 95, we plumped for a 9000 Anniversary. Corking condition, with all the right history and low mileage (82K)

Now some technical stuff:-

Is it possible to retrofit a cruise control kit, my mechanic says yes, and it's not too difficult as the last of the 9000's had a simpler system. If so where could I get a kit?

It has a Saab radio, and separate single disc player, can a changer be fitted?

Power upgrades, i.e. ecu upgrade from Abbot, speedparts or otherwise, do they really make a difference and how hard do they hit the mpg?

I had a computer in my dash on my FPT 9000, where there is an analogue clock now. It just gave distance to destination, av speed est time of arrival. It was a bit of a toy, but if I could find one in a scrappies, could I fit it? I assume it needs power/earth and a speed sensor?

On a different note, can anyone confirm the correct Bosch part number for my

Enough for now more later

Cheers
