I don't know why, but it reminds me of the Saturn Sky (the US version of the Vauxhall/Opel Speedster), with a Jaguar F-type feel.
It lacks the typical BMW feel of the previous Z4 and Z3.
I like it but I bet the production model:
- Won't have those wing mirrors
- Won't sit that low
- Won't have such a thin windscreen surround (due to lack of roll over protection)
