The dealer's service is terrible.
When I did the 5000 km service, I complained about something wrong with the gearbox (manual). They told me later the problem is over.
It wasn't over, indeed!
I checked at another service place to discover there is too few oil in the gearbox and the guys told me you're lucky it is not dead.
Something else, when I bought the car, the engine was not working well when the A/C is on. When I did the 1000 km service they told me it will be better, but until now when the A/C is on, I lose much of the engine power.
I tried with the main Daewoo service and another accredited centre to fix it, but in vain!
Finally, I think I was cheated. When I bought the car, the warranty said "3 years or 50,000 kilometers" In 2005, I learned that the three-year warranty covers long-life parts only.
