Wife wins, hands down. The only thing that I am really concerned with is the driving, She can have any floor plan she wants. WHen we had the TT, I picked the truck, when we were looking at the A's, I was concerned with the cockpit, towing and outside storage/access......
As for the cake, buy a cake mix and frosting and leave it on the counter, see what happens, like she said "you never know what will happen", however if you still have the same box of cake mix after, say, a year.......well, you just can't have your cake and eat it to! :p
