nope ....
bmw prereg is you pay they register under co name than transfer to ur name  .... no mileage.
Pre-own - yes, basically company high management drive those car

pre-own will be much lower and the prices is still negotiable ... just like use car with better warranty.
pre-reg, i think there is fix prices or very slight nego, as Co use internal for tax reduction than resales it (some tax grey area)

i get quoted discount 4-5k about there.
if habis they able to get from other branch. no need special connection. only certain hot sell model got.

Hapseng star have a lot of pre-own as they have many division (home, loan, plantation, mosaic n bla bla bla) ......
Yup u can ask around for pre-own but everyone is offering different Prices cause is used car.
for example last week HSS manager offer a 6month old c200 for rm 210k (i think 30k cheaper than brand new), but with some internal connection (me some how work with HapSeng before), able to get it at 19Xk

For Bmw pre-reg, basically i heard from friend, as they buy it as min 30k-80k cheaper (depend on model). assume pre-reg is a lot better as is BRAND new car with two name on the title ....

Pre owned does make sense to me. Wifey bought F30 320i LCI in Jan 2017, car is 2016 model, 6k mileage, RM190k OTR. Maybank loan 7 years 2.57%.

You have to compare second hand market for these

There is one listed ,M sport spec for 201,000
