Ha 
My first road bike was the used Peugeot UO-8 I saved up for when I was 12 years old.
That was stolen when I was 21. 
I replaced it right away with a very similar Peugeot that I rode until I started touring, and wanted a midweight tourer that fit me better. My new Specialized Sequoia (with narrower wheels than came stock) was my dream bike. In 1987 I got bit by the racing bug, and had a frame built for me by a local framebuilder. I rode both those bikes interchangeably until I burned out around '94 and didn't ride a road bike again for 12 years.
In 2006 I went to a retreat and rode a demo Specialized Ruby for three days, and realized that I'd been away from cycling long enough to love it again. I got new bearing grease, new tires, and new handlebar tape for my old race bike, filed down the brake pads and was good to go for the rest of the year. But I'd already had a taste of modern bicycle technology on the demo bike. I was amazed at how much had changed. My old race bike had first-generation indexed shifting that never worked exactly right. To go from that to brifters.... I loved the frame, but by 21st century standards it's heavy, and more to the point, it would have cost more money and a TON of effort to strip that frame down and build it back up, than it would to just buy a new complete bike. So three years ago Christmas I got a new bike.
