Air BnB rentals maybe outlawed or have to be registered in some cities you want to visit. Ensure you are booking something that is regulated/licensed.
You will need an IDP for each driver.
You may need winter tyres in some countries in March. Fines are applicable if you do not have them. However winter tyres in the warmer climates are not so useful. You may also need snow socks to over come the snow on the roads.

There are safety regulations you have to abide by too. every country is a little different. The younger child may need a child seat elevator and may not sit in the front in some countries.
That is here from the English Automobile Association.

>>I personally don't have a problem with a long road trip with hours on the road and visiting many places, with some short overnight stops. <<

Me too . . . but not two straight months of road trip w/ no breaks at all. A road trip is for exploring the countryside -- not city center to city center in most of Europe where a car is useless.

>> I was planning on looking for Airbnb so we can have free parking<<

Not very easy. The VAST majority of airbnb's in the cities you list are apartments and most of the time they won't have parking. Free, paid or otherwise.

You need to add between 10% and 25+% to almost ALL of your drive times. More if it involves finding your way through major cities. And you can't take the car into the city centers in some places in Italy. So in reality typical days would look something like this: from City A . . . The drive to city B (adding say 15% to the drive time you calculated), parking remotely, taking public transit or a cab to your apartment (shoots most of the day). The next day is free for exploring. The next morning you pack up, take transit back to your car and drive to to the next destination (adding 15% to the drive time) . . . and repeat over and over again.

The buy/holiday/ship car home scheme is terrific -- really is. But you need to design an itinerary that works. So either 1) modify/shorten the list of places you want to include, 2) collect the car in a more convenient location, or 3) lengthen the trip considerably.

My choice would be a combo of 1+2 -- fewer destinations over a smaller area AND starting out where you want to be, not in Sweden if you have no interest there.

AND -- I am assuming/hoping March was a typo. March to to July simply isn't possible.

I'm sorry, it's a typo error. I meant May-July. I wasn't aware that you can pick up Volvo some place else. Thought you can only do drop off. I wanted to do factory tour though. I'll keep working on it. We'll have 3 drivers. My daughter is 19 & son is 11.

>> We'll have 3 drivers. My daughter is 19 & son is 11.<<

You've mentioned that a couple of times -- I'm assuming because you are thinking 'road trip' like across the western US where three people dividing the drive/spelling each other can cover many hundreds of miles in a day.

That isn't what you'll find in many (any really) parts of western Europe. Cities in Europe are (mostly) very car un-friendly. Touring around rural Spain, or Provence, or Tuscany, or the Dordogne . . . absolutely.

Maybe you watched one two many episodes of 'old' Top Gear

Unless the 3 of you are Jeremy/James/Richard . . .

<i>I wanted to do factory tour though.</i>

I'd be amazed if Volvo wouldn't let you do the tour at the end of the trip rather than the beginning. What model are you getting? Some of them aren't actually built in Sweden (the XC60 is actually built in Belgium, then shipped to Sweden for the European delivery program.)

Sorry I didn't pick up on the date typo. My point is still valid, however - picking it up somewhere else might help in building a more reasonable itinerary, possibly with a minimal net cost differential.

Meant to add, I think the part about city driving assumes that you want to take your new car into the middle of some of these cities. I guess I'd say that what many people do is use the car for touring the countryside, and if and when you want to go into a big city - Paris, Prague, wherever - you stay someplace outside the urban core and use public transportation to get into the central part of the city in question. Most major European cities have very attractive towns on their peripheries where lodging prices are usually cheaper, where you can park a car, and still be able to enjoy the cities themselves. There are commuter trains that run all day in both directions.

I would not assume your 19-year-old will be able to drive, at least without paying a hefty premium. Have you checked this out with Volvo?

Volvo quoted $325 extra for 2 months of auto insurance and extended registration. I'll ask about teenage driver restrictions.
