1.5T has basic parking assist but not fully Autonomous parking. You'd still have to park manually. Note that fully autonomous parking systems require clearly defined lines and markings on the road / parking spot, and other people to respect the parking markers, both of which are rare in Pakistan. 1.5T also doesn't have side radars so any features dependent on that (like Blind Spot Monitoring, Door Open Warning or Rear Cross Traffic Alert or Collision Warning etc.)
Generally, you should be fine with 1.5T as well, but there are rare instances where the lower spec might be an issue. Like the recently launched Voice Commands feature is available for all 2.0 AWD and HEV models sold but only recently manufactured 1.5T are compatible with it. Not sure if this really was a hardware limitation or just product segmentation based on marketing.
As for booking, you can book now and you'll get delivery in March most likely so it would be the 2025 model.
