Same situation, 20 years in a company car scheme decided time to leave and buy my own.
Picked up a 2021 R-Line 2.0 Petrol about 6 weeks ago, before that had a 3 series diesel and before that an A4 with the same basic drive train as the Arteon.
Got to be honest compared to the A4 the 3 series felt like a tractor, I hated it.
The Arteon is fantastic, had mostly VAG cars for the last 20 years and this is my favourite model yet - getting mid 40s on a good run driving sensibly and plenty of oomph when you need it.
