Agreed but Hyundai did develop RHD but was not commercially sold in any market before Pakistan. Yes Nishat is the first one assembling and selling RHD.
Hyundai imported 3 RHD CBU's and one of them was displayed for public @ Lahore in March 2020 for the feedback.
Its a good sign we have a newer generation of Sonata while the other two models from Nishat are obsolete . Keep in mind, this current generation of Sonta have poor sales in its hometown and it didn't click well in North America as well. Infact Sonata used to be always a best seller in Korea but this generation falls behind. K5 from the sister company took over Sonata as far as sales in Korea while Hyundai Grandeur is also preferred by buyers over Sonata.
Thanks to crossovers and somewhat a polarizing design of the new Sonata as per many people. There is rumor that because of Sonata's low sales , upcoming facelift was probably canceled and Hyundai might be working on full model change with possible arrival earlier than planned.
There is due chance, CKD's for current Sonata were easily and quickly available to Nishat because of low demand in overseas markets.
Again, Nishat must be appreciated for their approach as far as Sonata.
