The Herald is capable of exceeding the speed limits so no point being faster. Once the engine is warm my 13/60 will pull away in 2nd and 4th is good from less than 30 to max, don't need more.
In a convertible you can't here the engine sound, just the sound of the birds,wind in the trees and the compliments of people walking nearby.
You are more concentrated on looking through the windscreen to notice the interior and you are sat on some of it.
As for the bonnet the bit that is different isn't visible from the driver's seat.
Ok, I'm biased.
Yes a difficult choice, I opted for the Herald because in 1970 I learned to drive, and passed my test in one although it was a saloon not convertible
