Hello.

I just have a quick question.  If you already have a car, and want to
add things to it after you have bought it, is it easy to do, and where
do you go to get it done?  For example if I have a car that doesn't
have a Trip Computer, but I want to have one in there to show things
like how much MPG I am averaging, range for remaining fuel etc, can
this be done?  Also, if I wanted to have better display
instrumentation, perhaps digital lcd speedometer and rev counter that
is backlit, where can you get this done and how much does it cost?  Is
it easy to do it yourself?

Thanks for your help

John
