Right before I proposed on Los Muertos beach in Puerto Vallarta at sunset with the ring in my pocket, I asked my now wife "hey if we ever get married, will you let me buy a Ferrari some day?". She said "sure why not" and the rest as they say is history. If I think back there was probably a minute or two filled with banter between my Ferrari ownership question and my proposal. In the excitement of the moment she didn't tie the two together but in her hindsight the timing of my hypothetical question made it seem like the only reason I was proposing was because she was going to let me buy a Ferrari. Of course she knows that wasn't true but she was a little sore for years about that. We did go to Italy on our honeymoon a year later where I insisted on Modena and Maranello being on our itinerary. To address the dilemma of the original poster, there are some differences between us. I always wanted a Ferrari since I was 12. It never went away, I had to wait until 40 something. Your desire by contrast came out of seeing your friend's Ferrari in your garage for a time. Nevertheless, I can empathize with your growing passion. All I can say is possibly you could use my story and say "See... at least I didn't do that to you!".
