The only thing that has gone wrong is the lifters when it is cold. Until the car gets warm, the lifters make a ticking noise. I am in Minneapolis, so it is cold here, and it does get annoying.
This is a very powerful car.
The craftsmanship really shows in this car. There is no way you would ever find an American auto that has +140k miles on it, and have it be as sharp and quality as this.
I have the Coupe and the coolest feature is the back windows actually are operational. Very cool.
This car is money. From now on I will only buy Acura or Mercedes.
For an engine that runs so smoothly when warm, it is very surprising how noisy it is on start-up. With age it seems more so. Use 5W50 synthetic oil, believe it makes a difference on engine life and wear, but it is very expensive.
