It might be a little squeeze for the del sol, but the question that I have to ask is where would you like to mount the screen? If you go the flip-out touchscreen (like the Pioneer, Kenwood models) you can use it with your laptop. Check out mp3car.com for the Xenarc or Lilliput touchscreens, they work w/ a USB connection and have VGA inputs (better quality over RCA). The laptop itself can be housed in your trunk or even under the passenger seat.
