can we get some help to deal with proper list practices please?

this may seem silly, but once again - porsche vs corvette:
is it just me, or does riding in a porsche (doesn't matter which model) make
you feel all high and mighty - above the average man?
i've been contemplating a porsche, but i'd feel stuckup in one - driving it

I'd like to know what performance one can expect from a 911SC(up to 83)
and 911 Carrera(84-88) as well as the 930 Turbo.
By performance I mean 0-100KM/H or 0-60MPH and top speed. I know that
straight line performance is not their forte, but would really like to

i've driven the Porsche Carrera and Turbo - needless, to say...there's an
obvious difference in the way they drive - lol
but i've never driven the GT3.
how does the GT3 relate in comparison to the Carrera and Turbo?
