In Puławy, Poland, where I live, we mainly get late-90s to late-00s cars from B- to E-segment, with age going down as the segment does. They're mostly German-import 4-cylinder manual diesels. The most popular cars in each segment seem to be VW Polo Mk4, Ford Focus Mk1/Mk2, VW Passat B5 and BMW 5-Series E39, but all have their domination contested (Polo by Opel Corsa C/D and Fiat Punto Mk3, Focus by Astra G/H and Golf Mk4/5, Passat by Mondeo Mk3 and 3-Series E46, E39 by E-Class W210 and V70 Mk2). Besides that, there is a lot of big 00s and 10s vans (mostly Mercedes Sprinter, Sevel Sud Mk3 triplets and Renault Master Mk2).
Where I live, the Honda Civic is by far the most common car. Most of them are 9th and 10th generation ones.
Where I'm from, Toronto, Canada, CUVs and SUVs are very common, usually from the past 10 years. The most prevalent are last-gen Honda CR-Vs and RAV4s, but older ehicles like the 2008 Honda Pilot and first gen Toyota Highlander are also popular.
No model in particular. I've seen pickups and SUVS from Chevy, Ford, Toyota, Nissan, and etc. Basically, if its sold in North America, I've seen it.
Here there are many Ford Fiestas, mostly new, and as I live near a JLR factory, there are a lot of new Jaguars and Land Rovers. There are a growing number of the latest gen Ford Focus too.
A lot of 90s/2000s mundane vehicles, alongside some modern vehicles as well, and the majority of them are from mainstream brands.
Mostly 2000s cars, from B, C and D segments. Most common B segment cars are Fiat Punto 2, Opel Corsa C, Renault Clio II, Peugeot 206, Citroen C3, VW Polo Mk4, etc. There are also some newer cars from that segment that are common, like Renault Clio IV, Citroen C3 II, Peugeot 208. Fiat Grande Punto, Renault Clio III and cars from 2nd half of 2000s are also common. From C segment, Renault Megane II, VW Golf 4 and 5, Peugeot 307, Opel Astra G, Fiat Stilo, etc. are worth mentioning. Renault Megane III, Opel Astra H, Fiat Bravo, Citroen C4 II and Peugeot 308 are common too. From D segment cars, common models are VW Passat B5.5, Passat B6, Renault Laguna, BMW 3 E46 and E90, Audi A4 B5, Opel Vectra, Peugeot 407, Citroen C5, etc. Minivans are popular too, mostly Renault Scenic, Opel Zafira A and B, Opel Meriva A, Citroen Xsara and C4 Picasso, Mercedes A-Class etc. Some models are very popular as taxis (Renault Scenic and Opel Zafira), mainly because of their cabin space. One thing which is still unique for Serbia, is that there're large number of Zastava vehicles. Most common are from 90s and 00s, with Yugo, Skala and Florida being the most common. Most popular engine choice is diesel, preferably under 2000cc. Reason for that are stupidly high reg taxes for engines bigger than 2000cc. Common cars with that engines are usually some bigger, luxurious cars, like BMWs, Mercedes, Audis and high end versions of middle class cars. Even most of petrol engines are smaller by capacity.
