Always glad to help!
On a serious note, I do keep an eye on what's around, just in case.......my shortlist to replace my Aero would be, in no specific order (probably all in the estate version):
Skoda Superb - roomy, and plenty of engine options
Mazda 6 - the excellent fuel consumption of the 2-litre petrol appeals - reports of over 40mpg from the auto
Honda Accord Tourer - IMHO looks good, and the Type S is no slouch, although manual only in this version (available in 160bhp)
Audi A6 - it would have to be the 3.0Tdi quattro of course
Hyundai i40 - roomy, but sluggish and thirsty as an auto
Kia c'eed - looks good, but has it enough poke?
VW Golf - as Kia
Seat Leon - good performance from 180bhp diesel, also available as 4WD
Ford S-Max - drives well apparently, and has a 2.2TDi with auto
I discounted BMW on cost grounds, the Insignia and Passat feel wooden, and I would have problems persuading SWMBO that a Mondeo estate would be suitable.
You might notice there's a wide variation! Sometimes I swing towards practicality, sometimes looks, sometimes performance......it'll be a difficult choice when/if we have to choose!
Having had the Aero auto for some time, I found that having a gear lever in the Insignia estate I hired recently was a novelty that soon wore off. And I've never tried a DSG box but having read around the subject, I am concerned about the hesitation from rest and the longevity.
TBH, my favourite among the list, all things considered, is the Accord Tourer - it's less common than a Beemer and looks good IMHO. If only they did a Type S auto....and I think the most practical is the Mazda 6. And the best performer is the Audi.
