Brakes needed replacing after 50,000 miles.
Dealer tried to get me to part with £500 for new brake disks, pads and a new clutch at the 60,000 mile service. Told them I'd wait a bit. Nothing was needed at all, so watch out!
Now got engine problems that are going to cost about £500-800 to fix. Problem is, no-one can do it because Daewoo UK are in administration. Be very careful!
The Nubira is a very good car. Fairly economical (~30-35 miles per gallon) but parts and servicing are a real problem.
As an update on the car above; I replaced it when Daewoo UK was wound up. I got £1200 for it after the car broke down when the dealer was test driving it! I was going to get £2000 in the part ex. The dealer, who said he used to work for Daewoo (or Halfords, I can't remember) said that the fault I had (according to him it was a dropped valve) is fairly frequent with Daewoos. I liked the car, but I'm glad to be rid of it. I got a Citroen Diesel Estate, which isn't as nice, but is saving me so much in running costs it's unbelieveable! Moral of the story is; don't buy Daewoos, they cost the earth to repair (and service) and only the dealers (or Halfords) will touch them!
