I was reading an article talking service problems on those 3 cars.. So I wondering if any F40, F50 or Enzo owners here or someone you know who has one of those cars had any of these problems. F40: -Cam-belt tensioner bearings tend to tighten up (causing the outside of the cam belt to scuff and gall against the tensioner = leads to belt failure) -The clucth hydraulics to fail( because the F40 bellhousing is magnesium and emits gases) -After 10 years all F40 are due for a complete water hose and rubber component replacement , regardless of miles. F50: -Electronic instrument cluster (major problem) - They said if some part of the dashboard electronics is defective, the car will go back to Italy for a 6 month $10.000 repair. - Defective front main seal (low miles F50 may not have had the update so better watch for that) - Last thing, the belly pan on the F50 tends to hide leaks by holding dripping fluids. Enzo: (in the article they said that so far the Enzo has had 5 factory recalls related: - Cooling fan update - The oil tank level dipstick - The front moveable flap connection - The F1 gearbox oil tank cap - The engine oil drain plug Oh yeah they said the F40 and the F50 is $10.000 for a check-up (for whatever problems). As for the Enzo..= under warranty.
