I think the BLM (baseline model) is to replace the 22-year old Proton Saga, that is why the TV advert says something about "a new Saga begins". This is a B-segment car, so it should not be competing with Persona which is placed in the lower C-segment.
Following current automotive trend, all B-segment cars now look damn funny, I believe they are bounded by certain external dimension, so, in order to maximise interior space they start to "grow" taller, and they pushed the passenger compartment right to the physical limit, and most manufacturers end up with cars looking a bit squashed, and the sedans will end up with ugly backsides... other examples of B-segment sedans: City, Vios, Latio, Accent, etc.
Well, just a thought here, could this BLM be a Savvy with a tail? Aarrgghh...
