Buy a new head unit, do a detail job (or paint depending on how "aged" your car is), and keep driving it. If you really love the car that much, you'll regret getting rid of it.

Pretty much no late-model cars have the same feel as an older honda. As safety standards increased, so did weight. Even an entry-level econobox these days is still going to have several hundred pounds on a EG or EK civic.
