In very simple terms
Japanese = reliable, cheaper to run, better at holding their value, boring to drive
European = less reliable, more expensive to maintain, lose more value, more fun to drive
American = unreliable shite that is dull as all hell to drive
Yes there are exceptions - Mazdas for example are great to drive and they're Japanese. Some American cars are also ok to drive, but they dont generally sell them here.
I, like you, have pondered the PT Cruiser. I like the retro styling and they're actually a practical use of space with a large loading area at the back. They came in two engine sizes, a 2.0ltr that also appeared in the Neon and this was a dog. Under powered, overly thirsty and agricultural. Matched to the hapless auto it was completely defeated by hills and would search up and down the gearbox screaming like a two year old thats lost it's teddy bear.
It also came in a 2.4ltr that was put into the mid sized Sebring. I drove a Sebring in the US and on the open road it was an unruffled performer with a lazy lope that was relaxed at highway speeds up to 70mph. It didnt have any legs above this, but hey, you dont want speed. If you're going to get a Cruiser, then look for one of these.
The rest of the car is a bit plastic and cheaply made and will likely fall apart much quicker than a Japanese car, but on the plus side they are a unique looking vehicle.
Personally, if I was looking for a reliable vehicle, with a large back for carrying stuff, I'd go for a Mazda 6 diesel in manual form. Great to drive, nice to look at and fuel economical and they come in wagon form and have huge amounts of space. But they're going to be more expensive to buy in the first place.
