You can be easier on first by never changing straight from neutral
to 1st. I select 2nd when I am about to take off then 1st. I never get
any nicks or crunches. I do the same when I am going to reverse out
of a parking space.

I can't remember who told me of this trick but it was an old sprite owner.
