The urge to change is always there but sometimes needs to be suppressed. If the hay bails are still involved then something with a posh interior would be a challenge.
Carrying capacity
Agile and rewarding handling
Enough power to be good for overtaking on the narrow main roads down here.
Previous shape C class estate with 350D engine in a nice trim ? Slightly older good condition AMG 6.3 Estate would be my first option. The older V8 is a naughty beast but beware as it goads you into revving it to hear the noise and feel the cam change. By which you are going fast.
BMW 5 Series Estate with 535i or 530/535D engine. I know you disliked the 3 series you had but the 5 series without M suspension is a much smoother experience. Actually the 5 Series GT (length of an estate but hatchback design. may be interesting, they are not so popular but are well priced and nicer than the standard 5 Series due to the long wheelbase.
Octavia Estate is quite good with the petrol GTi engine.
