We definitely need to do a better job translating AWS to people new to AWS. As mentioned before, the instance you used was not an instance with an 8-core processor, instead it was an instance with 2 virtual CPUs hosted by a system using that processor.
One great feature of AWS EC2, is that you always have more than one option when it comes to the instance you can use, and it's always best to try a few different instances to see what works. Regarding the BMW scene (v2), it can be rendered on a c5.9xlarge for $0.018 in less than 2 minutes, an option much faster, and cheaper to use.
In your particular case it wasn't the cheapest option, since you had access to a local company renting actual GPU hardware in 24 hour blocks, and you were able to make full use of that time. While you could get really close to that performance and cost with multiple high-end c5 spot instances, it would still be a bit cheaper from your local farm. Outside of your particular case, compared to any of the other rendering platforms out there, it is still significantly cheaper.
