Where find engine code, you mean the dvvt/ vvti label on engine cover?
Engine code is on the engine.

ii. What's your opinion on cheap, lasting, good used cars including example model( s) ?
Toyota altis,Vios, Camry.  Perodua myvi,Alza, Bezza

iii. Your opinion on Toyota Corolla, & Honda Accord both ~1993- current yr used ones, eg can last long, fuel consumption low, alot spare parts & cheap spare parts etc?
Toyota will lasts longer than Honda. Cant compare Corolla with Accord because Corolla is C Segment, Accord is D Segment. You can however compare Corolla with Civic and Accord with Camry.
Why pound foolish, smoother from Myvi w/e gen 1.3-> 1.5 how significant, like can feel earthquake?
The biggest feel would be the torque. Also 1.5 has a smoother gearbox ratio compare to 1.3. When you travel at highway speeds, the engine rpm runs lower, thus smoother and better fuel consumption.

I'm planning to buy a used car below RM 35k. Is Peugeot 208 2014 model a good buy? I prefer an continental car. Which car is the most worth purchase below RM 35k?

The engine code.

Toyota has 40 percent controlling stake in dahaitsu. Reently, toyota controlled more than 50 percent, and the new myvi n bezza use toyota engines, so u will notice the old myvi uses dvvt, the new myvi n bezza use vvti. Both are the same technology. but since toyota commands control over dahaitsu now, it can put vvti badges on dahaitsu cars. Daihatsu in return controls perodua.

A1. " dvvt" , as in Toyota's DVVT without intelligence?

A2. So dvvt, ie dual vvt change to vvt but w/ intelligence?

A3. If A2= yes, is up/ downgrade?

A4. Anyone know i. Current, ii. 2nd hand, Toyotas, corolla, camry etc, Hondas, civic, accord etc, Peroduas, myvi, bezza, axia etc mostly direct injection engine/ no?
