Possibly, all depends on cost like everything in life. Porsches just dont do it for me in the looks department.
Now some would say that the E89 is not a sports car anyway (I dont care what bracket people put a car in, I will buy something that I like not what people say it is) so moving to an F-type would be a similar car. To me a sports car is a Ferrari, a Lambo, a Mclaren etc not a BMW.
The reason for not moving into another Z would be that we bought ours when it was 3 years old. We wouldnt really want to buy another Z that was older than 3 years old when we bought it which would mean going for one of the last in production from 2016. From what I have seen advertised there is not a lot of black Zs and even less with a black interior. Call me boring, I like black cars.
Maybe just time to move on and try something else. Although that will more than likely be in another year at least.
