You are right. It sounds better also. My view is that Wills' car is the correct written version, and Wills's car is the correct spoken version.

Um not sure why you pointed me to the grammarbook. I have no trouble with apostrophes but as I said in my earlier
post - to paraphrase, lol - bah humbug. I have taught the English language and think a lot of it is
unnecesarily complicated and silly and it's (note "it's") time to have a makeover, but the pedants won't let us. 
At least it's not as complicated as French where you can't even say Bill's car, you have to say the car of Bill (le voiture de Bill)
Also, in French the posssesive pronouns "my", "your" (singular) and "his/her its" have three different forms (mon, ma, mes; ton, ta tes amd son, sa, se) depending not on who is doing the possessing but on on whether the object(s) possessed is/are designated masculine, femine, singular or plural.
"Your" plural doesn't distinguish between feminine and masculine but still has two forms (votre and vos) depending on whether the object(s) possessed is/are singular or plural.
Once you've learned French, English grammar is a doddle.
