This 1966 [Checker Marathon](https://fridayswatchlist.com/search?make=Checker&model=Marathon) A-12 Wagon sold for $24,500, and that's strong money for a modified classic like this.

The Checker Marathon is a unique piece of automotive history. Originally designed as a taxi, this A-12 variant is particularly rare, especially in wagon form. The big draw here is the 350ci V8 engine swap from a 1990 Suburban. This upgrade not only enhances performance but also makes the car more enjoyable to drive compared to its original inline-six powerplant. The three-speed automatic transmission offers a smooth driving experience, making it practical for both car shows and daily cruising. With just 56,000 miles shown (though the mileage is listed as TMU, or true mileage unknown), this Checker has plenty of life left in it.

The bidding was lively, with 35 bids pushing the price up to $24,500. Given the rarity of a V8-powered Checker, this price feels market-correct. For context, similar modified vehicles can vary widely in price, but this one seems to have found a sweet spot among buyers who appreciate its unique blend of style and performance. While it may not be the cheapest option on the market, the engaging driving experience and distinctive look justify the price tag.

Community feedback was positive, with comments highlighting the car's appeal. One user, @kbstrawn, remarked, “That is a wicked good deal on a beautiful – and rare – Checker wagon!” This sentiment reflects a shared appreciation for this specific model, particularly in its modified form.

For buyers hunting a similar car, always check the quality of the modifications. A well-executed engine swap, like this 350ci V8, can significantly enhance value, but poorly done modifications can lead to headaches down the line. Look for documentation on the swap and any upgrades. A clean build can make all the difference in both enjoyment and resale potential.
