Well I bought a brand new P500 last week. Have about 9 hrs on it so far and 87 miles I was reading the owners manual and it says to get first service at 100 miles...recommended or could I let that slide abit? Also has anyone tried using a better quality of gas? Does it preform better at all? Also one more thing I realize that I top out at 41mph once it hits 42+ say going downhill i get an engine brake which pulls me back should i just get use to that?
