What happens when you want great fuel economy, rock solid reliability, and don't want to sublet a kidney for it? You buy a four-cylinder, that's what, jabroni. This week's challenge is to find the absolute best four-cylinder cars money can buy for less than a $4,000 budget on eBay. Bonus points if they're all one color.

Here are the rules:

  • Selections aren't limited to simply 'cars' (kit cars, trucks, and military/commercial vehicles included)
  • One entry per post.
  • Cars must have a realistic selling price under $4,000.
  • Cars must be operable/easily restored to running condition.
  • Completed and sold listings can be included.
  • You can add modifications, as long as it doesn't go over the total budget.
  • Write a short reason why your car is best four-cylinder powered car for less than $4,000.

Now go find a car that has a name that doubles as a colloquialism for frugality.

I'll arrange the best selections afterwards. You have until the end of the weekend.
