I had a 2021 M40i but had my head turned by a 2020 F-Type P450. Lovely car, but 6 months in I'm chopping it in for another M40i. I think the Jag looks and sounds better, but it's a heavy old beast and the B58 is unequivocally a better all-round engine, and more fun to drive. Also, the overall build quality of the Z4 is way better and the interior a nicer place to be. No questions I'll miss the throaty V8 and gorgeous (but ageing) looks of the Jag. This time its a 2023 Skyscraper Grey with all options. Looking forward to rejoining the G29 cold.
