I’ve had two as company cars and put over 80k on each from new.
First was 5 speed first generation 2.0 136hp ts diesel. Lovely to drive, held road well and very communicative steering.
Last was a 2010 facelift (black centre consul) 2.2 163hp ts2 diesel. Better refined, fair bit faster, lots of torque and generally a nice place to be.
Neither put a foot wrong bar a recall on each fixed free, although the interior is a bit plasticky and uninspiring.
Great to drive though.
However, I had a petrol Octavia vrs between the two and would take that over any 6 short of the MPS.
