If you are a new PPL remember your experience level will increase quite quickly and you MAY grow out equally quickly of the aircraft you choose at this stage.
Not always the case as some buy aircraft to quickly build hours then dispose of the aircraft. Buy well and sell well and short term that can work to your advantage
Again do the sums and see what suits your pocket and the hours you intend to fly !
It maybe more prudent to rent to start
