Hello every1 I'm Jane

Well today I bought my new ( to me anyway, lol) 95, fto gr, with a full veilside body kit.
mongoose exsaust, lowered on apex springs, plus a nice little alpine sound system.
Only downside if anything is that i bought it off e-bay, so its buy it as seen sort of thing.
theres no guarantee something wont fall off it tommorow.
altho to be honest the 50 mile drive was ok. only real problems so far seem to be, there are these additional rubbers along the top where the doors close ( like wind deflectors if ya know what i mean ) well on my trip back, having opened the passenger door for the first time this strip just fell off from the top, it seemed to be held on only by bits of double sided tape, But this itself was hiding another problem...! That the bit of plastic trim that forms the top where the door or glass of the door closes onto ( forgive my some what abstract and over descriptiveness, jus hope it helps) well theres a huge deep scratch on that trim, i will tommorow look to see how the other one is attached. but how hard or how expensive are bits of plastic trim like that, can i order them from mitsubishi. Im soooo new to this, especially an import the other thing is my cobra alarm that when i press one button on the fob, it just sets the alarm off an the other.....
i have no idea. I dont want to go straight to a garage to get ripped off. my boyfriend said that when he was driving behind he saw the odd puff of smoke now and again, could that be related to gear change, i mean i see lots of cars on the road new and old do this.....
should i worry. any advice would be soooo welll appreciated
