The G4NE engine number is located at the front where it connects to the gearbox. This engine is a true exclusive, with very few similar cars produced. Its main problem lies in the lack of spare parts and competent repair specialists. On forums, there are frequent complaints about various electrical glitches. Owners also constantly encounter oil and coolant leaks. The exhaust manifold is located close to the cylinder block, making the possibility of wear and tear quite likely.
