Not too much overthinking involved.
1st Plus 4 - Had an insurance policy mature and decided a 50th birthday treat was in order. Knew I liked the Morgan look so reviewed the models available at the time and bought one sight unseen based on the lovely images.
2nd Plus 4 - On holiday in Cornwall went for a peek at the nearby Morgan dealer and fell for a tasty showroom model so swapped the Plus 4’s
3rd Aero S5 - Had a glass of red too many while perusing the classifieds, made a cheeky bid on an Aero and had the offer accepted.
4th Plus 6 - Perusing the ads again, came across a dealer bought perfectly specced Plus Six so arranged a part ex for the Plus 4
All except the 2nd Plus Four were bought based on the images without seeing or driving. Worked out fine but probably not recommended.
