There have been no problems with this car to date.
This car is a great value. It feels like a luxury car for the price of a mid-size. There is very little cabin noise, and it rides extremely smooth.
The only down-side is that the engine is perhaps a little underpowered.
While a great car, the Epica is no longer being made. As a result, there is no used car market for it. Thus the value has dropped in half in less than two years.
