Thank you very much for your considerate answer.
A couple of months down the road the seller got in touch with me because he had lowered the price. I went ahead and bought it.
It's been with me for about two weeks and it's great. It was in great condition (altough not as good as yours) —mostly original pieces in good shape. I hope I can ride it for a longer distance soon rather than just my commute.
Greetings.
