I have owned several 991's & 997's and had an early 992S in 2019.
I then changed to a Taycan 4S which I got in June 2020 and I have never looked back. In fact I still have it nearly 3 years & 26500 miles later which is the longest time I have ever owned a car. There is just nothing else on the...
Why? . I've just paid my £61726 final payment but have had offers of circular £88K-£90K for the car.
That makes it the one of the lowest depreciating car I've ever owned.
Vossen recommend 21x9.5 ET42 on the front which is 18mm out more than standard.
Anywhere between 14-18 mm more out on Front & 12-15 more out on Rear is good.
