Fuel pump at about 70k kms. Was replaced by the dealer within warranty coverage.
I owned a 2001 Lanos from October 2000 to September 2003.
Car was purchased from Daewoo's exclusive dealer in Oman (they have since lost the sales franchise, but continue to provide service, repair facilities).
The car was great value for money:
Air conditioning was terrific, especially keeping in mind Oman's hot desert climate.
The car handled very well even at higher speeds (traffic travels at 140 - 150 kms / hr on many of Oman's freeways).
Power was more than adequate, even surprising I would say coming from a 1.5L SOHC.
Trunk space was pretty good for a car of its class, interior space was adequate - 3 adults on the back seat is tight, but expected for a car in its class.
The resale value was a disappointment, though.
I own a daewoo 2001 LANOS SE and I don't have problem at all now it is 92000T and only problem I'ved encountered was the compressor which I replace recently. power durability and performance are all acceptable on this range of economical car.
