Character

ES9 3.0 V6

"406/407/607/C5 V6. PRV-derived V6. Timing belt on a V6 = expensive replacement. Oil leaks. Cooling system complexity. Beautiful engine but high maintenance costs. Specialist knowledge needed."

TU3 1.4

"15 million TU engines made. Simple cast iron block. Timing belt (not chain). Head gasket can fail on very old units. Incredibly cheap to maintain. 206/207/C3 workhorse. Over-engineered for what it does."
