They had a used fully loaded L&K estate at Pulman Skoda not that long back. Looked like someone had ticked every box they could 
I had nowt against the Skoda except the depreciation cost being marginally higher and the A4's interior is a big step up. Considered the Kodiaq too. Bottom spec Skoda vs bottom spec VW/Audi gap is significant, but once you go up the trim levels and the more expensive engines, adding Skoda's Quattro equivalent, there's about 10% in it which is eaten up by higher depreciation.
Higher depreciation on Skodas has always negated RRP savings vs VW/Audi for most models.
That fully loaded Skoda estate will lose someone a fortune if it's not a demo.
Who buys at RRP prices these days? Most Audi's, VW's & Skoda's, etc, have anywhere between 10 and 20% discounts new. As do most other manufacturers.
Relating depreciation to RRP is a pointless exercise and it almost never matches reality.
As for Skoda's, we've always done really well at resale time. In the case of a Yeti, it actually only depreciated 28% from what we paid new over three years and 36K miles. Another vRS Octivia estate lost 51% of its new cost after nearly 4½ years & 48K miles. I'd be surprised if many Audi's and BMW's, etc. would have done any better.
Relating depreciation to RRP isn't pointless - it adds context to the reason to buy new or not buy new. Buying a £40k RRP car new that'll be worth 60% of RRP after less than a year is nuts, unless you're getting a 30+% discount.
My last 11 cars have been bought brand new because they've been slow and steady depreciators, bought with 12-16% discount and still worth more than half RRP at 3 years old.
Almost all big cars (including the Skoda Superb ad Audi A4) are bought new by fleet at big discounts, rather than with private money, and plummet in value initially.
My experience when viewing the alternatives to Golf GTD/GTI/R etc within the VAG umbrella has been that it's just not worth buying a new Skoda or Seat over the VW or Audi equivalent because the lower RRP has been countered with lower levels of discount and higher levels of expected depreciation.
If an Octavia VRS is similarly equipped to a Golf GTI, but RRP (or for used, current selling price at the same age) is £5k less, is it a cheaper car? Yes and no. If you can get £1k bigger discount on the Golf and it's worth £5k more 3 years down the line, you're better off with the Golf.
Same principle applies to the Superb vs the A4 when I was doing my research about what big cars to consider.
Right now, if I were to buy either car, we're pitching an A4 Avant 190TDI Quattro S-line S-Tronic against a Skoda Superb Estate Sportline Plus 190TDI 4x4 DSG.
The Skoda has an RRP of £40740, has a 4 year GFV of £11394, and if you shop around, you can get about £8k off a brand new one, or £10k off a pre-registered one with a few hundred miles. A 9-12 month old one is £24k.
The Audi has an RRP of £41300, has a 4 year GFV of £15780, and if you shop around, you can get about £8k off a brand new one, or £10k off a pre-registered one with a few hundred miles. A 9-12 month old one is £25.5k.
They have similar levels of tech/spec.
So you can see above, if you buy new or pre-reg, the initial hit is about the same for both cars. Buying a year old and keeping for 3 years, you're going to be a grand a year better off with the slightly dearer A4. The interior (not just talking about door card plastics here, but seats, dash etc.) is far nicer on the A4, but mechanically they're the same.
Unless you massively prefer the exterior looks of the Superb over the A4 (I think they both look ok,- hard to get excited about a barge of a car like these are - not a fan of the Skoda front grille shape), why would you buy the Superb in preference?
Cheapest car isn't necessarily the cheapest car if you think about what it costs you over the time you have it. I picked that A4 over the competition because it'll lose me £3k a year in depreciation and I liked it more than anything else in the same segment at price point. The Skoda would cost me more than that.
The Yeti does hold its value well - it's a niche car that's far more popular on the used market than the rest of the range. Most marques have a car that bucks the depreciation trend - for Ford it used to be the Puma, Fiat has the 500, I did very well out of my Sciroccos vs what the MK6 Golf was fetching.
If I could get the Skoda for a grand a year less depreciation than the A4, I might've picked the Skoda, but that's not the case.
