I have to raise the top under a bridge to avoid getting soaked if caught out in the rain. It takes forever. Stay above 30mph and the rain goes straight over the top.
My manual MX5 hood in comparison can be raised in 5 seconds from the driver's seat.
I recently saw a dry state TR8 being restored in the UK. The restorer searched for rust with an endoscope but found none, even though the sills were barely covered in primer inside.
