The Nissan 300ZX is among the best Japanese sports cars ever built, but it has all the problems of a MINI Cooper. It’s rear-wheel drive, turbocharged, and mid-engined, and it’s not known for its ease of repair. There are two problems with the 300ZX’s injectors that make it a hard fix. Nissan isn’t the most expensive car brand, but it’s definitely the most difficult.
The hardest vehicle part to repair is the engine. Changing the engine is an expensive proposition, which is why many people opt for remanufactured engines. Other difficult parts to replace include the intake manifold, turbocharger, valves, and the cylinder head. Lastly, the transmission is one of the most complex parts of a car, so repairing it can be a challenging task.
