Yes woh baat bhi hai k popular ho tou qeemat barh jati hai
You have to see which risk are you willing to take.
Option A : You buy it now before price increases and it quality is not upto the mark and within a year mechanical issues and parts supply issues etc and low resale and you sell it and lose 3 lac
Option B : Price increases 2 lac and then you buy it after it has good market response and no issues. You spend 2 lac extra due to price increase
Option A and B dono mein kahin na kahin se apka paisay extra lag rhay hain, kis option mein kitnay paisay bachtay hain ya kitnay extra lagtay hain no one can give you an exact figure so you have to decide which risk are you willing to take
If i have the money i would get a Toyota and have peace of mind and agar paisay nai hain then i would consider Alsvin k jitnay paisay hain risk le letay hain
If you have the Yaris you can always sell it on invoice price or slightly above in the time span of 1-2 years and shift to Alsvin
