Character

W8 4.0

"Passat W8. Two VR4 blocks merged. Most complex VW ever. 4 timing chains. Ignition coils. Oil leaks. Cooling system. Near-impossible to find parts. Beautiful concept, terrible ownership."

1.9 TDI (ALH/AHF/ASV)

"Legendary diesel. 500k+ miles documented. Simple, efficient, nearly unkillable. Belt-driven."
