Yeah... I had BMW 323i '84 model once and the maintenance doesn't hurt (much if you have a honest mechanic!). But my current mechanic ask me to go for E28 525i or 528i instead of E30! He said E30 have lots of problem.... he's driving E28 as well! When I'm around his workshop, I ask the owner of W126 300SE and he strongly recomment that model to me, saying that it's cheaper to maintain than BMW or Volvo more comfortable and economy! The bottom line is, every owner have their own judgement about their car (Audi, from Ingolstadt and Boggysv, thanks man!) it's very hard for me to make up my mind since all of them have their good story!
I think every car have their own value to appreciate and up to the buyer to deside which one to op for, right! Even buying a 2nd hand Wira if not carefull, it's going to make hole on both of your pocket! Thanks to all who contribute, now I just need to blindfold myself and pick the one among all the model suggested! That's the best way to do.... hee...hee....
