Gear conversion Troll E

Hello together, I have a question where maybe someone can help me further: I’m about to buy a Saab 9-5 2.3 Troll E (year 2000, 110’000km, 250 hp). Unfortunately, the vehicle has an automatic transmission… Finding a hand-operated model seems almost impossible, so I wanted to ask if anyone has experience in converting vending machines into hand-operated vehicles, if this is recommended at all and maybe also how high the Kos Do you have a Troll E with the 4-stage automatic? If so, how does it go about sport and agility and so on? Thank you for your help Greetings to Emperor Lu
