Overall the car is extremely well valued and from my short experience with it I would purchase it again. There are however three problems that I have encountered so far with my car.
First, the gas mileage as already mentioned in almost every other review, is poor. My first two tanks of 50 plus Liters got me only 400 Kilometres (13L per 100km). This might be because the engine is new and once you reach around 10,000 km you will see the dealers estimated range, I sure hope so.
Second, I have encountered the same problem as many in terms of headlight condensation. My dealer has said it is easy to fix they will drill a hole for the water to escape. This problem not only exists in the Epica, but all GM products.
Third, When I picked up the car I noticed the brake routers has a lot of rust. This will cause accelerated wear on the pads and they were not willing to fix the problem. This problem also exists on any other car that has sat for a while not just the Epica.
