How to answer if you didnt sell your car. "If you sold the vehicle during the year, do all Capital Cost Allowance Chart amounts above apply to a single Class 10 vehicle?"

Not sure how to answer this question. I didn't sell my car and there is no option to leave it blank.  Someone said that if you did not sell it, leave it blank. There is no option for blank. It's either a yes or a no.  There is a big difference in the return whether you answer yes or no.

If you only own one car, the answer would be yes. If you have more than one class 10 car, then the answer would be no.

I have 2 cars.  The other car is an older car which I traded in for this one.  For the old the car, I answered yes, the CCA amount for that entry was for a single class 10 vehicle because I sold it and for the proceeds section, I put $500 because it is the trade-in value.  The car I am referring to in my question is the new car.  So is that correct, yes for the old car and then no for the second car which I didn't sell?  They are 2 separate vehicle entries.  And for the total cost of the new car before taxes, do I deduct the trade-in value? For example,
$17,000 new car
-     500 trade-in value of new car
-----------
$16,500 net difference
