Welcome to Talk Morgan Steve.
The 4/4 Sport is a very nice car and the best price point of the Classic range; however, some owners have been lured to spend a little more by the larger engine of the +4.
As a used vs new proposition, the 4/4 Sport (new) vs a preowned +4 makes for an more difficult choice. Equally, at this time of year and with 20% VAT looming, you may find some dealers willing to be a little more flexible on asking price if they have cars sitting in stock (so a new +4 may be less than the standard MSRP).
Driving both will make up your mind for you.
