They spend very little money on design and development by copying foreign cars wholesale. They fool consumers into associating their cars with more expensive, better made vehicles, and fob stuff off on them of very poor quality, reliability and strength (those crash test scores of zero are NO joke).
More affordable? Yes. But there's a reason for that. They're more affordable because they're very cheap to build... care to wager why?
I talked to a couple of people who use JAC vehicles... can you say "overhaul" in less than a year? And this is for funeral homes, who don't use the vehicles daily or in traffic (probinsya pa ito!), not like rental fleet or cargo fleet owners.
And have you seen the sheetmetal on these things? I saw a Chinese SUV the other day that looked exactly like a Prado. Except Prados don't look like they're made by Francisco Motors (no offense to them, but...)... the sheetmetal was rough, poorly finished, and looked hand-painted. I've seen better work by backyard lateros.
That's why some Chinese manufacturers try to entice people into buying their vehicles by stating that they have an "Isuzu" engine or a "Nissan" engine... but this simple change raises the price a lot... uncomfortably close to the price of an Isuzu or a Nissan with the Isuzu or Nissan engine as stock...
It's a false economy. You can buy a DVD player for 3,000 that will last 60% as long as a 7,000 peso DVD player... but how long would a 1,000 peso DVD player last? If it only lasts a few months before it starts getting erratic, then you'll be on your tenth player by the time the 3k or 7k player conks out. There's a point at which cheap enough becomes too cheap, and you end up spending more because you end up with junk that needs replacing.
Only time will tell if any of the Chinese automakers will step up to the challenge of producing vehicles that will meet international standards of safety, emissions, and reliability. In the meantime, they're producing junk to make money, like the Koreans of a few decades ago... over time, the Korean companies have grown. Those who were serious about making changes and concentrating on quality have survived and prospered. The others have fallen by the wayside.
Sure you want to gamble on a Chinese company that doesn't have the word "quality" in their mission statement?
