Secular, i.e. diocesan, priests take no vow of poverty. Yes, they could buy, or keep if given, a nice car. If their bishop had other policies or thought it unseemly and told them to sell/get rid of the car, then through obedience they would need to do so.
Religious priests take a vow of poverty and do not own possessions. If their order owned a nice car, they might have the ability to drive it.
Not all religious take vows of poverty, only mendicants.
Benedictine monastics do not vow poverty. These vow stability, obedience and ongoing conversion, but not poverty. They own exactly what the abbot of the monastery tells them to own as part of their vow of obedience. They are typically co-owners of all the property of the entire monastery so they can't really call themselves poor.
