Thanks so much everyone, especially Moeks for his extensive input (very helpful!). My wife drove our last Superb so no issues there. It was actually her first car after she passed her test. She was a bit daunted at first but after some 'drive a proper car or get the bus, woman!', she gave in and absolutely hates small cars now lol.
I've spoken to a couple of dealers today. My local Skoda wasn't very helpful, even though we visited in person. That said I've found that every single time I've visited in the past (sales and service). I swear they don't earn commission, they're the most disinterested bunch of salesmen I've ever met. They act like you're an inconvenience and that they're doing you a favour by selling you one of their cars, and just sort of stand and stare at you with one word replies to complex questions, if they answer at all.
I asked about test driving a TSI, even a 1.8 or similar if needs must. I explained I'd owned a mk2 Superb and was thus more interested experiencing the TSI + DSG combo to see how they felt, rather than it needing to be a specific case of a 2.0 220 Superb + DSG per se. A TSI Octy would do, even. The reply was "I might be able to get you into a 1.6 diesel next week". Um... Yeah that's close enough amirite?!
I then called Simpsons in Preston and the experience couldn't be more different. The guy was genuinely friendly, and as soon as I told him what engine I was after he perked up. "Oh a proper engine! Don't get many requests for those to be honest. Always nice to hear, that! We don't have a Superb 220 sorry, but I can take you out for a long hoon in an Octy VRS with the same 220 2.0 and DSG on Monday if you fancy a trip out?".....
THAT is how you sell a car.
I'll be making similar enquiries around the local Fords for a 2.0 Ecoboost to make sure I make an informed decision, but it really is looking like the Superb is the better bet if I want to find any life at all in the car. Shame, as I bet that engine is a little peach in a manual (especially in a Focus chassis).
Thanks so much again for the replies thus far. I'll update when I have news.
