7 seats are always a plus.
The only viable options you have are Sorento or Oshan X7. Glory, Tiggo, and Santa Fe should be avoided imo.
Oshan right now seems to be selling quite well and you will often see it in northern areas families coming on trips thanks to the very large interior and 7 seats.
You can also get it brand new, the facelift 7 seater future sense that also comes with radar / adaptive cruise.
Sorento will be used and does not have adaptive cruise.
I would say visit a Changan showroom and test drive the Oshan X7. It’s quite powerful too thanks to its turbo boost and you will not find it sluggish.
If you are not a brand name fan and if you like Oshan in person go for it. Also read posts in the dedicated Oshan X7 thread.
