as I understand you are allowed to bring in the car twice for six months at a time with either six months or a year between visits, unsure if the car after two visits ican be registered in another name ie your wife's name wether car is allowed back, my understanding is that it's not as they take not only owners detail but also engine vin etc and it's the car not the owner or driver. crazy rule. if you are retired or are a working for certain universities as a lecturer different rules may apply but check those out before you buy.
