There are a few things you can do to make sure that when you show up to a car guy’s place, you’re the star of the show. First, be sure to have a good attitude - this is especially important if you’re trying to impress the guy because he’s likely the one who will be driving your car. Second, dress appropriately - this includes having a nice outfit and looking presentable. Finally, make sure that your car is in top condition - this includes having no dents or scratches, and being clean inside and out. If all of these things seem like too much trouble, don’t worry - there are plenty of other ways to impress a car guy. Just remember that it takes some effort and effort on your part, so don’t expect everything to go automatically for you.
