It depends on the choice of people. Most people & mechanics are not aware as to how to deal when a daewoo is having a "technical" problem. There are limited mechanics who are expert. Like in my city Karachi, there are 4 - 5 well known mechanics who know each & every bit of the car but other than them only a few mechanics only agree to work on daewoo. The most technical area is the electrical wiring where most mechanics or electricians feel hassle to diagnose the problem and as a result either they make alternation or fail to fix. Alterations will include removing of sensors & making direct connections resulting in CEL or performance issues. In the case of my car, I have tried my best to maintain it but still there are some wires in my engine bay which are cut off & left open & they were done by the previous owner. I have no idea that where are they coming from & what was their function. Also there is lots of "Jugaar" in the wiring but still my car is functioning properly because the sensors & wiring is functional & I do not compromise in that section.
Regarding parts, again people think they are expensive but I disagree. Though the parts are available at limited dealers like Aslam autos at plaza in karachi but very basic parts like fuel pump, timing belt, bearings, oil / air filter, brake shoes & pads etc are available at almost every where but parts like clutch/pressure plate, shocks, springs, sensors, suspensions parts, lights, drums & calipers etc are only available at dealer. My friend has a 99 city & his clutch/pressure plate costed 5500/= while my racers set was around 4000/= & korean made. Fuel pump is 750/= (Chinese) & 1500/= (Toyota). Brake pads for 600/= & brake shoes for 800/=. Air & oil filter for 400/=. Timing belt for 300/=, Radiator (New Chinese) 5500/=. Regarding body parts i.e lights, bumbers, locks etc, they are a bit expensive but can be found at the dealer or kabli. Dashboard & interior parts are expensive & not easy to be found. i heard that the complete dashboard costs around 35000/=.
In my opinion, the issue of maintenance (limited expert mechanics) & availability of parts at limited stores is the reason why daewoo is easy to purchase, hard to sell & hassel to maintain in the views of a common man. Only the person who knows the secret of Daewoo will love to buy it. Maintaining a daewoo is not that difficult but sometimes it becomes "galay ka phanda"
