The AWD system requires a fluid change every 30,000 miles. If the previous owner skipped this, the pump can fail, effectively turning your R into a Front-Wheel Drive car.

If you are cross-shopping years, the 2016 model introduced several critical upgrades over the 2015 version:

Like most direct-injection engines, carbon can build up on the intake valves over time. If the car has over 80k miles and feels sluggish or has a rough idle, it may need a walnut blasting service. 4. Clutch Condition (Manual Only)

Replaced the proprietary MDI cable with a standard USB port.

Perform a hard launch on a safe surface. If the front wheels spin excessively, the Haldex is likely faulty. 2. Water Pump and Thermostat Housing

Lightning-fast shifts and superior launch control.

You want a "grown-up" performance car that can haul groceries, handle snow, and embarrass Porsches at a stoplight.
