It is a bit of a vague request/question but one of the things you must do before every drive is let the engine/oil warm up before you go roaring off like a race car driver. Don't use the windshield from to assist you, or anyone else, when getting in to the car. Older, less fit, or just clumsy people may try to balance or aid themselves whilst lowering themselves in to the car. Don't let them.
Speaking of getting in the car. It's easiest if you open the door, sit down in the seat (perpendicular to the car), then swing your legs in. Exit in reverse order. Another method is to put the right leg in first all the way to the tunnel, slide down in to the seat, then get your left leg in.
Start building strength in your forearms. If not your arms will get tired from waving to everyone who honks at you and/or gives you a thumbs up.
Warn your wife or significant other, if you have one, that you're about to become a rock star and you will garner the attention of hotties everywhere you go. Just tell her, "It's not me, it's the car.".
Oil changes and valve adjustments once a year or every 3K miles. Use fuel additives like Startron or Stabil at every fill up. I also use SeaFoam in the fuel to keep everything nice and clean. I don't use Stabil because I drive year round but I use SeaFoam at every fill up.
