I may consider a 2 year old one (let it take the big depreciation hit first), if I were to keep my current Astra K until it was around 8, then this would be possible.
No doubt there will be mainly petrol & hybrid engines then, with maybe an electric choice too.
I can't see myself buying another Astra K, as I'm happy with my current trim & engine set up.
I hope PSA don't go any firmer with the suspension set up...

I actually prefer the look of the K's now, 3 years plus on from their first manufacture I'm like that sometimes with new model introduction, must be down to familiarity.
