Vmax at 306 Built. 95 only 180?

Hi, I recently bought a 306 Bj. 95 with 88hp used (111tkm). With a lot of good will (and a long run) he barely manages the 180km/h. Is that normal? Or how fast will yours be? Before I drove a polo with 60hp and he also managed 180. If that’s less than normal, does someone have an idea about what that might be? And what else: My left mirror is over, I have now looked at it like it’s stuck, I see that the complete and has someone a good address to buy a new mirror? Peugeot wants 120 Euro, at Ebay I have already seen it for 50. (electrically adjustable and heated). I am grateful for every tip on the two questions because I found nothing in the search. Thanks already. mfg
