### **Pros and Cons of Buying a 2010 2016 Infiniti EX35/EX37/QX50 (RWD, Propeller Shaft, VIN 370001BN0A)**
#### **Overview**
The **Infiniti EX35/EX37 (2010 2016)** and **QX50 (2013 2016)** are luxury crossover/SUVs based on the **Nissan NV350 platform**, sharing mechanical components with the **Infiniti G37 sedan** and **QX60**. The **RWD models** (with a propeller shaft) are rare and often sought after for their **sportier handling, better weight distribution, and lower center of gravity** compared to AWD versions. The **VIN 370001BN0A** suggests a **2010 2012 EX35/EX37** (or early QX50), likely with a **3.7L V6 engine** (268 272 hp) and **6-speed automatic transmission**.
