Re: HD radio
Let's be brutally frank here... if you were a child in the UK in the 70s, I think you could say that of just about any British or Italian car older than about 6 months. (I was originally going to type "that had been driven off the dealership forecourt" but realized that on balance I was probably being too harsh).
Regardless, 5 years was practically "Telegram from the Queen" territory for them.
