There are enough SUVs on European roads to prove it's possible. There are also countries like Switzerland or Luxemburg that have higher average incomes than the US, and still prefer Porsches or Mercedes to SUVs. Looking at the countries with slightly lower GDP per capita like Spain or France, you can restrict statistics to just the upper classes, and any group income-matched to the US population will have just as many garages but still far fewer SUVs.
