It may have an Achilles Heel in its timing chain guides, but it isn’t something that scares a true enthusiast with a determined attitude. If you have one of these amazing V8, Quattro, luxury sedans, you are sitting on a goldmine of potential, just make sure you take care of those weak points first.
