^^ Takara Challenge and Lotus Classique are not all that common (I've seen a lot of old bikes; never heard of either of those), so I was curious. Google Image found one really large example of each, both on the same blog, as it turns out.
You just can't hide from the teh googles, I guess.
BTW, if you've always wanted a Univega, there's one close to me in your size. Let me know if you like me to check it out for you. It's been on the local CL for about 3 months, so he's probably ready for an offer. http://olympic.craigslist.org/bik/4292011898.html
