Can confirm, rebirth's consumption is high. We use it on a very light foot inside Islamabad and we get 10-10.5 in winters. Also can confirm, cat needs to be serviced but not after 10-15k kms but after 50 imo. Also also can confirm, rebirth's suspension system is very weak unless driven very carefully.
Again, new is new. Old is old and will need to get SOME work done after buying. So keep the additional cost in mind. There's no ''just buy and drive'' in reality. It's ''buy and drive, discover all the issues, get them fixed, discover some more issues, get them fixed, then drive.''
This is just our experience.
