Solid Micro Project: 1956 BMW Isetta 300 Bubble Window

Some cars manage to be cool without even trying. Enthusiasts agree that classics like the First Generation Mustang, the Chevelle SS 396, and the Plymouth ‘Cuda achieve that status while barely raising a sweat. Although this 1956 BMW Isetta 300 Bubble Window doesn’t possess the performance or overwhelming physical presence of the previously mentioned models, it is undeniably cool. This beauty has sat for years, but it has avoided the rust issues that often plague these classics. That makes it a prime restoration candidate for those preferring their cars in concentrated form. The seller has listed the Isetta here on eBay in Elyria, Ohio. They set their BIN at $18,500 with the option to make an offer.

When I spotted this Isetta, I decided that writing about it was a mercy mission. Scotty G is our resident microcar enthusiast, and I had visions of him purchasing the vehicle as his next project candidate. Therefore, I guess that I am saving him from himself! The Isetta was part of a move by European nations to produce small, light, and affordable motor vehicles following World War II. Some efforts were pretty lamentable and disappeared almost as fast as they emerged. However, the Isetta was an exception, remaining in production for an impressive ten years. BMW adapted the original Iso design, reengineering most aspects until its model shared no common components with the Iso. The first BMW rolled off the line in 1955, with the company building 161,728 of these little gems before production ended in 1962. The first owner ordered this Bubble Window example in 1956, and it is a surprise packet. It has sat for many years, and there is evidence of emerging mild surface corrosion. However, the image gallery confirms the absence of any penetrating rust, suggesting the build won’t require cutting or welding. The retractable soft-top serves two purposes, both of which are pretty important. It weighs less than steel, a crucial consideration considering the modest engine that powers these classics. The Isetta also lacks decent ventilation, and with such enormous expanses of glass, occupants can quickly feel quite “cooked” on hot days. The glass looks excellent, but the top is tired. The trim is intact, although some pieces are begging for a trip to the platers.

Sadly, the seller supplies no engine shots, but we do receive valuable information. BMW initially released the Isetta with a 250cc single-cylinder engine from its motorcycle range. It delivered 12hp, so it wasn’t considered fast. However, the company upped the ante in 1956, slotting a larger 295cc powerplant into the Isetta, boosting the available power to a dizzying 13hp. A four-speed manual transmission fed the ponies to the rear wheels, with the factory quoting a top speed of 52.8mph in that year’s Sales Brochure. The seller confirms that this Isetta doesn’t run and that the motor doesn’t turn over. Whether the situation is salvageable is unclear, although it would be worth trying to protect this classic’s originality. The deal includes a freshly rebuilt carburetor, which is a small bonus.

The Isetta’s Sales Brochure demonstrates how far safety has advanced since 1956. These cars feature a single bench seat that can accommodate up to three people. However, the company states that the rear parcel shelf would be ideal for transporting a small child. No, I can’t see any potential safety issues with that approach! The seller states that the interior is complete, but it requires a retrim. That shouldn’t represent a huge challenge, because everything required to return the interior to a pristine state is readily available.

I won’t kid myself, because I acknowledge that this 1956 BMW Isetta 300 won’t appeal to everyone. However, microcars enjoy a strong following in the classic world, and pristine examples typically command sale prices that demonstrate that the Isetta punches well above its weight. Rust is a common issue, but this car is rock-solid. It would be ideal for someone contemplating a project build, but with limited space to work. If you fit that description, is this one that you may consider?
