335d advice

[Falconer]

I am looking at replacing ageing Subaru Impreza WRX with something less boy racer and with much better fuel economy.
Tempted by 2-3 yo 335d at around £20k. AWD essential, performance seems even better than the Subaru and getting to the age when auto would suit me.
Do any advice? Is it a good drive? Realistic mpg? Any expensive design faults waiting?
Any help appreciated . Thanks

Wife has one of these, estate version
40 mpg overall, done about 40k miles now
It’s not a sports car, so don’t expect go cart handling or anything, but it’s fast, comfy, comes with lots of toys. Not massively big but big enough for 2 adults and 2 kids
£450 tax if you get one that’s newer than March 2017, watch out for that
