Sorry I cant comment on the Acura as they don't have them over here :iono:
In therms of the MK5 GTI mines just past its first birthday with just over 7000miles on the clock.
Faults to date have been :-
1: 6CD packed up (replaced under warranty and I suppose this could happen on any car) Its now replaced with a VW Ipod prep so it doesn't matter :wink:
2: I have had a whole set of injectors in my car replaced at only 6500 miles. It was back into the dealer 3 times with a really strong petrol smell before they finally diagnosed the perforated injectors and now all is well again
Has any of the above put me off my GTI ? Not one bit I love the thing to death. My last 5 cars have all been VWs or Audis and I've had no real long term reliability problems with any of them :headbang:
In summary if you want a car that stirs your emotions EVERY time you drive it then buy the GTI. If you want 100% reliability then go for the Acura (which I'm assuming is a Jap origin motor ?)
