Hello Saab experts, would like to buy me a Saab convertible as a Daily Rocker. Unfortunately I have absolutely no experience with this brand. Here are a few questions: Which BJ is recommended? Automatic or circuit? Petrol or diesel? Are there typical vulnerabilities to which you have to pay attention? Spare parts supply? I found some in the net with Hirsch Tuning. Is this serious and recommended? To me the 150hp models seem a little undermotorized for such a heavy car Thank you Peter
