I don't necessarily have a problem with creating a mid-range roadster, be it a small Miata-fighter or a 2+2 to beat the few four seat drop tops (Chrysler, Mustang, Volvo, Audi S4/A4) and call it a Healey.
The Healey was a derivative car, so there's nothing really bad about basing a Healey on BMW (or any high-quality Japanese or German) platforms. The key would be to create a fun, well positioned car.
And as I've harped-on time and time again on the BCF, it's a mistake for companies to simply try to copy a legend, or a classic car, because it only appeals to those that wanted one back in the day. The key to good auto business product management is to increase the market, and that is done by creating a great modern product in a good segment. A modern 2+2 sports convertible that is less expensive than a 3-series Bimmer, but more european than a Mustang or Sebring would sell very well, and be very true to the Healey 3000 name. (Plus it could use a 3-liter BMW engine to stay true to the 3000 model!)
