Volkswagen Passat W8

Back in the early 2000s, Volkswagen thought it would be a good idea to stuff eight cylinders under the hood of its Passat mid-size sedan. Enter the W8. With an engine born from two V-4s spliced together, it's fun to drive, but a nightmare to keep running. But if you have the means, we'd say go for it. Here's a wagon version for sale on eBay right now.
