He or His?

[iamwkk]

Should it be "he and his wife's car",
or "his and his wife's car"????
It seems that both make sense.
Please help.
Thank you very much!!

You will hear people saying both. The possessive makes more sense logically, but some don't like having the repetition of 'his'. I would use 'his'.
