Thanks! I’m content with ICE cars for the near term. Mazda MX-5, Nissan Z, Porsche Boxster, Mini Cooper, Civic Type R, Toyota FRS/Subaru BRZ, etc. all fit the bill.
On the electric side, the e Golf proved that it’s possible, and the electric Mini Cooper also fits firmly under 1500 kg. So there is more hope for the future!
Port forwarding helps connect to peers but it’s not strictly necessary.
As for organization and removing, symbolic links could work but if port forwarding is over your head, filesystem nuances might also not mean much to you.
My advice would be to focus on what you can do easily. Can you copy the files instead of moving, at least for a few days, or until the seed ratio has passed 1.0 or 2.0? If you can’t do it for everything, can you at least do it for the files with lower numbers of seeders?
