A friend's mother used to have a 2000 model. It was the VXL trim and was petrol driven. I've had experience of travelling with her and trust me that car was way way better than what we are getting now. The finishing, the plastic quality, each and everything was excellent. It was bought brand new just after Khyber was discontinued and it was sold in around '08 when they moved abroad. The car was only driven around 30,000 km on its original tyres and even the bumpers were scratch less! I saw that car some 6 months back and the way the bumpers were hanging and the way the person was driving it, I felt real bad for that car.
Another friend had a 2001 model in LSB color shade and it was a lovely car. Now 2 of my friends own EFI ones, and trust me the quality check at PS is just pathetic. Engine is nothing that much extraordinary as per my opinion, however they seem to be much more responsive when revved at higher rpms.
I was having a picture of the ad when Cultus was launched in 2000 by PS, will share it Insha-Allah if I find it.
BTW Here is a picture of the ad in newspaper when the new version Cultus was launched. (With clear lens indicator and tachometer in the speedometer cluster)

Rear suspension is different, Cultus uses independent struts where as Khyber has torsion beam in the rear.
Brakes are also quite different when it comes to performance, While braking in Khyber one can easily feel that "more bite" where as Cultus lacks it.
This seems like the 1SZ-FE that came in the previous gen. Vitz.
It was an inline 4 cyl. engine. 1 KR-FE is 3 cyl.
Yes there was, however there were very few of them. If my memory serves me right then they had almost all the same features as in the VXL trim.
