Hi all,It has been awhile since I last logged in.My E39 still runs fine and awesome. Just that sometimes it still gives me the battery gremlins (see my thread at E39 forum).Anyway, back to the topic, I found a BMW 328ci UK spec at a used car lot.I am very interested at the car but I have some questions to ask as I am not familiar with the car. The car has done a decent mileage (ca 50k miles from new), which I hope it did as the conditions of the car say so (the black leather seats look immaculate)Hope those familiar with this BMW Ci E46 coupe can give some opinion:1) The car comes with BMW navigation but the screen becomes orange and no display except the clock. May I know how much to repair this?I know I can always change to the new Dynavin but I like to keep the car original as it comes with Harmann Kardon sound system as original.2) The instrument panel display is showing some signs or sun burnt (the door open warning area). Can I replace with a used unit and may I know how much?3)The rubbers around the rear quarter windows has melted due to our unrelenting sun. May I know where and how much to replace these items should I buy the car.4) Anything else I should check for a car this age?5) Lastly, how much should I pay for this car?The dealer wants RM50k but I am not sure that's the fair price considering the car is 13 years old. I am willing to pay him RM40k or i will just walk away.Btw it is shodded with 18inch BBS rims.many thanks in advance for any honest replies.Cheers.
