Newbie! Request a purchase help with a 9-3 convertible

Hello municipality, I play with the idea to get a Saab convertible as a second car. The 9-3er to year 2003 is for me the most beautiful vehicle from this series. I find nasty the current one. I want to invest max. 10′ Euro, for a year from 2000, with mileage max. 100` On offer are mostly the 150 HP 2.0t. I don’t know the brand – it would be my first Saab. Now a few questions: – Are there any year-dependent details, changes, improvements of the last series from which I know So it’s better to buy a 12/2002 than a 7/2002 because it had xyz of changes since 08/2002? – Are there typical flaws of this model you should pay attention to when buying? – For some cars (mobile.de) I once saw a co-painted and once a black front fenste frame in silver vehicles. What is it with this? – How vulnerable is the cover? – With the 150PSler, can you take it with automatic or is it too lame? I am happy to be on your help and your counsel. Greet Andrew
