I just got myself a F82 M4 Competition 2020 70reg san merino blue with full carbon fibre kit fitted by BMW one owner from new, but Still have my E92 335i m sport manual mineral white all original, but the M4 Competition is a different kind of beast and as you say everybody complements it and overs want to race you. I love the san merino blue it just pops.
Congrats on the amazing spec M4! M cars are just so different to “regular” BMW cars even when compared with a 335i. You will love it! Nice to keep the 335i as a daily if you can and enjoy the M4 for weekend drives perhaps
Keep thinking about moving on from my F80 M3 Comp but just can’t bring myself to sell it…F8X are just an amazingly combo for the money, period - your M4 looks a nice example, enjoy
