For years, diecast car collectors have faced a common frustration: leaks. Tiny cracks in the paint, or faulty seals, can lead to the dreaded oil stain on your shelf. But the landscape of diecast collecting has changed. The ‘Next Gen’ Cars 3 diecast models boast improved leak-resistant features, promising a longer-lasting and more pristine collection.
What Makes ‘Next Gen’ Different?
The secret lies in manufacturing improvements. The Next Gen models often employ better quality materials, enhanced sealing techniques, and stricter quality control. This leads to significantly fewer leaks and a much more durable product. While no diecast is completely foolproof, these improved techniques significantly reduce the risk.
Improved Paint and Seals
One of the most significant changes is the improved paint job. The paint used on the Next Gen models is often thicker and more durable, less prone to chipping and cracking, which are common causes of leaks in older models. The seals around the wheels and other moving parts are also more robust and tightly fitted, preventing the leakage of internal lubricants.
Material Upgrades
Many Next Gen Cars 3 diecast utilize upgraded die-cast metal alloys that are stronger and less prone to warping or bending. This added structural integrity further contributes to the improved leak-resistance, preventing stress fractures that could lead to leaks over time.
Stricter Quality Control
The manufacturing process itself has undergone improvements. Stricter quality control checks throughout production help identify and eliminate potential issues early on, reducing the number of flawed models that reach collectors. This translates to a higher overall quality and reliability.

But how can you tell if a Cars 3 diecast is a ‘Next Gen’ model? Unfortunately there isn’t a single, clear marker on the packaging. However, there are a few clues you can look for.
Identifying Next Gen Models
- Check the packaging for mentions of ‘improved durability’ or ’enhanced leak-resistance’
- Examine the model’s paint and finish. A smoother, thicker coat is a good sign
- Look for any model numbers or codes that might indicate a newer production run
- Read online reviews and forums for information from other collectors about specific models
- Compare it to older models. You might notice some subtle differences in construction

Sometimes, the best way to identify these is through trial and error, comparing models and reading feedback from other collectors.
Are they worth it?
The higher price point of Next Gen models is a valid concern for collectors. However, the increased durability and reduced risk of leaks translate to a longer-lasting investment. If maintaining a pristine collection is a priority, the extra cost might be worth it in the long run. For those who want a car that will endure, they are a good option.
Ultimately, the decision of whether or not to invest in Next Gen Cars 3 diecast models depends on your individual preferences and budget. However, the significant improvements in leak-resistance make them a compelling option for serious collectors looking to build a lasting and beautiful collection.
Caring for your Next Gen Diecast
Even with improved leak resistance, proper care will extend the life of your diecast. Avoid extreme temperatures and direct sunlight. Gently dust your models regularly and store them in a cool, dry place. A display case can offer additional protection from dust and accidental damage.
