Well, it's not the Alsacian car maker, Bugatti, it's just a boom era European thing. If it fits you and you don't have to pay shipping 149 doesn't seem to bad for a nicely equipped generic mixte. bummer about the tires and tune up. I'd try to take those off the final purchase price.
If you're close enough for a local pick up then you're close enough to go over and have a good look at it and maybe even a test ride.
If you can get to the guy's place about the time the bidding ends, you can make up your mind and throw in a last minute bid or wait till it's over and give him a low ball offer.
It looks like a decent bike to me.
