The answer to this question depends on the specific situation and personal preference. If your wife has a car purchase index and you want to register the car in her name, it may be more appropriate to put it in her account. This may help to avoid some troubles and restrictions after buying a car. However, if you are more willing to register your vehicle in your own name, and have car purchase indicators and related qualifications, then it is ok to leave the vehicle in your account. In this case, the vehicle will become your personal property and you can use and dispose of it freely.

To sum up:

Choosing whether to leave the vehicle at your wife's house or your own depends mainly on your personal preference and actual situation. If your wife has a car purchase target and wants to register the car in her name, this may be appropriate. If, on the contrary, you prefer to register the vehicle in your own name, and you have the car purchase index and relevant qualifications, then it is ok to leave the vehicle in your account.
