Bit late to this…
I’ve got a diesel vRS as a company car and it’s really good but very dull but in my mind no duller than the diesel BMW’s Audi’s etc that were an alternative. It’s good because it’s brisk enough, is really big, pretty well specc’d etc. It’s a competent car and is pretty comfy. The quality is fine and is a big step up from my previous Ford but I don’t think it feels as solid as our 330. I’ve got the hatch and it’s pretty vast although I wish I’d got the estate because I think it’s better looking.
It’s not fair to compar an Octavia to a 5 series because they’re a different class of car. A chap at work has just gone from an Octavia to a 520d and keeps trying to do the same…trouble is one was £23k and the other £42k. The Superb is a big step up for the Octavia but is bloody vast. I can’t believe how big they are.
As for space, BMW are the masters of the reverse tardis (massive on the outside and diddy on the inside). I’m a big fan but struggle to get excited over the four pot engines. Their big deli you point for me was the six pots. I’d struggle to choose a X20 over the alternative VAG car. However the X30/5 is a no brainer for me. The current 8 speed gear box is rather impressive too.
If you go into the change with your eye open, then there’ll be no disappontment. There will be cost savings because it’s a cheaper car (although BMW do this too if you look hard enough and the nine M Sport cars have some pretty nasty leather on the steering wheels and gear stick).
