I thought I'd chip in with my experiences, after seeing Enobar do the same, around purchasing and owning a new Superb. There might be something here that saves problems from befalling others or gives you a little more information to work with.

It's broken out into chapters (sorta) to give an idea of where I'll head, and the first two parts are below.

-Initial research
-Booking a meeting with a salesman
-Visiting the dealership
-Following up with the dealer
-Next closest dealer
-A quick spin
-Ensuring the accessories are factory
-The "dealer pass-off"
-Some followup
-The wait


Initial research
It starts in January. I wanted a wagon and was initially focussed on a Commodore Sportwagon. No need for the V8 as I already have one, so V6 it was. My cars have always had a limited slip diff so that was on the cards as well.
Please Mr Holden, could I have a manual V6 wagon with L.S.D, in that lovely green colour you have?
No. V6 manual with L.S.D is sedan only.

Ok, thinks me, I'll go all the way to the top of the tree to the Calais. The Calais has everything. Can I have a Calais V with V6 and L.S.D in green please?
No. Only a V6 manual and any V8 can have a L.S.D.

Ok, thinks me, I'll have to go to a V8 *sigh*. Can I have a Redline wagon with L.S.D in green please?
No. We don't do Redline in green.

By this time I was a bit frustrated and didn't really want a V8 so it was back to the research.
I would be disowned if I ever purchased a Ford so the list included anything around the cost of the Calais wagon that wasn't clutching a Blue Oval.
The Mazda was ugly, the Hyundai a bit garish inside, the Subaru a bit nanna and on and on.
Then I found the Passat and quite enjoyed the look of the front. The diesel had the most torque so that went on the shopping list. A mention was made of a sister car named Superb so that went on the list as well.
What followed was an orgy of YouTube and web sites. Wheels magazine was useless as it's just a big brochure.
My favourite clip was this:
2015 Skoda Superb Combi 4x4 - Test, Test Drive and In-Depth Review (English) - YouTube
With some others:

I even watched non-english clips (https://www.youtube.com/watch?v=1B_V5cZVIiE it gets fun from the 5 minute mark) to get a feel for the cars on my list.
So now it's time to take a look in the steel. My plan is to just look, no test drives, until I narrow down my list to two cars.
It's no use driving lots of cars that I don't really like, it just wastes time for everyone.
I didn't know it at the time but that plan was setting myself up for failure.


Booking a meeting with a salesman
It’s coming up to Easter long weekend so I reason that many people will be away and I can take my time looking at cars. I’ll target three places - the VW dealership, the Skoda dealership (both within walking distance) and I’ll have a last ditch attempt with Holden to see if things have changed. If things go poorly in the steel, then I’ll wander around the other dealerships and browse.

VW answered quickly and professionally, and Mr M would meet me first thing in the morning before he’s even had his coffee. They didn’t want any other details.
Skoda answered after a few rings but Mr B would be away that day so Mr X would help me. They requested a name and number that I supplied.
I didn’t bother booking a time with Holden.

Now to brush up on another couple of clips I had found in my research, and wait until Saturday arrived.
