The experience is going great. I love every moment of driving it.
Maintenance has been good so far. The car is in mint condition right now and therefore doesn't need any major maintenance.
So far, I've had new transmission fluid put in, new engine oil, new oil filter, new air filter, new cabin filter, new brake pads and some other general maintenance items. I also put in new coolant when I bought the car, just for peace of mind.
The car is running flawlessly right now and I'm very happy that I bought it.
The driving pleasure is incomparable to any other Japanese or local car in the market. The day I bought the car, I absolutely fell in love with it. It drives smoother than any BMW or Audi in the same category. The seating position is spot on. Everything about it has a certain level of perfection to it even though its a C Class. The seats are very comfortable, the steering response is great, the throttle responds quick and most of all, it rides very smooth over almost any kind of road. Even the doors make a deep 'thud' sound when you close them instead of the hollow bang that PKDM cars make. The engine sounds great and has a deep note to it during hard acceleration.
All in all, the experience so far has been very delighting.
If I were to buy a car in the same budget now, it would be a facelift, petrol BMW 7 Series E66.
I'd be glad to answer any more questions you might have.
