I also had the same experience. I REALLY liked the look of the Boxster since the 981 and had been planning on getting one as soon as my mortgage reached zero. I found the 718 styling a side-grade in the aesthetic department, but was put off by all the reviews/forums stating the lack of 'soul' and terrible engine noise.
I test drove a used 981 first, and was underwhelmed. Hopped in the 718, and both my wife and I were in love. I immediately realised that I was buying a car for myself, not for all the Porsche purists on the internet.
Congrats! Hope you love it as much as we do!!
I had a similar experience but test drove the 718S first. I simply loved the power, handling, confort, style and of course the lovely sound. Then, I test drove a beautiful 981S. I was immediately turned of by the low end torque (also mid end...). Of course, the sound was nice (with PSE) but it was far from being able to compensate the lack of power.
I find it funny when those who heavily criticise the 718 for its sound call themselves "purists". Some may also call "purists" those who want decent power (by 2018 standards... and they are high) for the money and criticise the lack of low end torque of the 981.
In the end, everyone should buy what they like. No one should criticize those who choose something else or even criticize what they choose. Continuing to fiercely criticize what a group loves is a lack of class ... especially coming from purists ...
Anyway! enjoy your 718!!!
