Ok, this really is a PSA. This set is/was sold at BMW dealerships. But, as of the moment that I am writing this, there are a few on eBay and they are a great price. These cars are extremely well done for how inexpensive they are making the set a great value. Especially if you like BMWs.
This set contains four premium detailed 1/64 scale BMW M cars. The paint quality is really good, the tires are rubber, the wheels are prototypical, and the lights are inserts. They do have plastic bases but they still have some weight to them. Overall, they are very impressive looking little models.
As far as I know, these are brandless which is why this set is flying under the radar (until now). Take a look at the pictures. I also featured these on a YouTube video. So if you’re not into it, cool. If you are, snag up the few that are left on eBay.
