my mate was driving my 500s today and told me it full foot and sometimes there is no power, sport mode doesnt do that much, and he also told me since my car is a ex demo with only 8ks when i got it from the dealer it has 630ks, he told me the mechanic hoon in the cars etc which has got me worried as i blacked out my tail light with stocking and found a heap of dirt underneath the tail light also he found that my right day time running light has water in it and the left has a crack i have not driven the car because im suspended till next month. the dealer drove it to my house aswell. do i have something wrong as in the power and sport mode.
