Octavia VRS Replacement…

I’ve had my mk3 Octavia VRs estate for about five or six years now and it’s been absolutely faultless. The problem is, it’s a diesel and it isn’t ULEZ compliant 🙁

As I work in what’s going to be the extended ULEZ zone in London, I’ll need to look to replacing it, as much as I don’t want to!

Any suggestions for a Skoda, apart for the obvious newer Octavia?

I’m commuting 35 miles each way, mostly motorway, and whatever I buy would ideally fit a couple of mountain bikes in the boot or on a tow bar carrier. Something with fuel economy like the current Octavia would be great, it averages about 55mpg. 
 

Are the smaller petrol engines any good in the Karoq and Octavia?
