So 280PS is 276hp, and £30000GBP is about $47211USD or $53484CAD. If the pricing holds true Honda can pretty much not expect to sell too many Type Rs. For that price I can buy a 9th gen Civic Si and drop at least $10000USD into a turbo and other goodies and make way more power and still have about $15000 to gloat about over the Type R owners.
If it was a hand-built 500+hp Mugen race car that Soichiro Honda built himself then maybe $45000+. But only if it had navigation. Non-navi? Forget it.
