I have all of the Gaston Lagaffe albums (Viggo in Norwegian) except two or three. To me, it's blatantly the opposite. I felt that the very first gags were uncreative and nowhere near as ingenious as the later ones. Also, there were no cars appearing during that first era. When he got his car, though, it all changed drastically. Later elements, such as the gaffophone, Mesmaeker running-gags, antics with Longtarin, the cat and the seagull etc. made the series even better. Ps.: there isn't a single K70 appearing in Gaston Lagaffe, so I can understand why you dislike the later ones
