Looks a little like a first gen Daihatsu Copen, and I mean that as a complement: https://en.wikipedia.org/wiki/Daihatsu_Copen#First_generatio...

I'd call it a Porsche 356 Speedster homage. But the Copen mostly likely drew its inspiration from the 356 as well.

The 54HP is right about what a 356 would have made with the larger engines, and the price with VAT is inflation-adjusted, roughly identical as well.
