I think your Octavia is the first-gen one, am I right? That might explain the build quality issues. Either that, or you're a really unlucky owner. All modern Skodas are based completely on VW components. Engines, chassis, most interior fittings, you name it.
The new Superb is actually a very good car. My dad and I went for a test drive of that a month or two ago and he came away very impressed. Build quality is solid as a rock, the ride is pretty good, it's dead quiet inside the car, the DSG gearbox is really smooth, the 1.8l turbo engine is quite responsive, considering how much weight it has to lug around, and it has MASSIVE interior space. I'm 180cm (6ft) and my dad 187cm, and I had plenty of space to actually stretch out behind him! And I truly believe the huge boot can swallow everything including the kitchen sink.
But anyway, back on topic, yeah sometimes car prices can be pretty ridiculous. The price you quoted in the first post, is that how much the Corvette costs from a dealer over there? Or did you simply convert the US price?
