Are there rules about how many people are allowed to sit in a car?

Your car came with a manual, which states how many passengers it fits, what weight you can put on the roof (no passengers are allowed on the roof, btw), what your tyre pressure should be etc. The number of passengers allowed is the same as is stated in the manual.

No, this is Switzerland, so as long as you can the doors to close you're fine (beware, that includes the sunroof - no heads poking out allowed!). But if you have more people in the car than there are seatbelts, the extra occupants have to wear a cowbell round their neck and yodel at intersections.

OK, seriously, how many people do you think can legally travel in a 5-seater? The clue is in the name...

Of course the rules in Kansas may well be different...

Most of Kansas City is actually in Missouri.

Thanks - Kansas rules are rather strict about this! (for the record, Kansas City is in both Kansas and Missouri - though the one in Missouri is the famous one!)

Another question -

Is a permit necessary to buy a car in CH?

Also

Diesel or Gasoline?

also

Auto or Manual (Stickshift)?

Many thanks!

Well, we have fit 11 in my Ford Focus wagon!

If they are strict in Kansas, how do you imagine they are in Switzerland?

I don't care where Kansas City is, but your profile says that's where you are.
Yes
these questions are pointless without more information...

You might some useful information here or here.

It depends on what the car was designed to run on.

Manual. Automatics are illegal in Switzerland. It's assumed that if you can only drive an automatic, you really shouldn't be on the road.

You forgot to ask about car colour.

Black or dark grey are fine but you're taking a hell of a risk with anything else.

HTH

It's very simple. Two people in a 2CV. 4 in an Audi Quattro. I'm glad I drive an XC70 - very difficult to be over capacity.

Since when did Kansas City become Switzerland. Why is necessary that what they enforce in KC is the same as here.

Somebody mentioned that Kansas city was in Mo so mentioned that there are many dimensions to the city. I didn't mean for you to care...

A valid question - thanks for asking for clarification -

Diesel vs Gas:

Are Diesel cars more common in Switzerland or Gasoline powered cars? I heard from someone that Diesel is cheaper than Gas but I see that there are fewer Diesel options autoscout.

Auto vs Manual:

It seems that are a quite a few Manual transmission cars around here in CH than what we're used to the US. From a car resale value perspective what is preferred - manual or auto?

Cheers,

Diesel is more expensive than petrol, but of course your consumption is lower, so you might find cost per km is lower. If you travel to less wealthy countries, diesel may be easier to find than super-unleaded.

It makes no difference to resale costs - Diesel/Petrol/Manual/Auto. Well, almost no difference. If there's a differential for a particular model new, that will remain, to a lesser extent, for resale prices.

Switzerland is one of those places where if it it's not forbidden, it's obligatory. Hence the comment re: if it's a rule in Kansas...

Gasoline powered cars are more popular. IIRC the market share of Diesel powered cars is somewhere around 30%.

Unlike the surrounding countries, Diesel is more expensive per liter than gasoline.

First of all, manuals are much more popular here than in the US.

But what's better from a resale value point of view depends on the car you're looking at. A Fiat Panda automatic is probably hard to sell and so is a Mercedes E-Series with a manual transmission.
As a general rule of thumb: The smaller and less powerful the car, the more popular are manuals and vice versa.
If you want to find out about a specific model it's probably best to do a search on autoscout.

I drive a Renault Espace. No numbers included. Needs a lot of fuel to get her into orbit, but it's fun.

Thank you Mark75 for some terrific answers!

Only in CH, everywhere else (D,I,F,A) it's the opposite.

Tom1234 - I liked your humor at my cost !

That'd be the less wealthy countries I mentioned. Diesel is more expensive than petrol in the UK as well.
