As someone else stated not sure a high end single din radio would be much of a benefit for you. If you are just wanting the looks.... visit the different radio manifacturers (Alpine, JVC, Kenwood, Sony, Pioneer) and see what you like. I am also a Hugh Denon car audio fan, loved their stuff back in the day.....

If you do go that route or get another radio and decide you need more power there are numerous small, light and good sounding small amps that can easily be added and also removed when the day comes to move on. Many are so small/light that they do not need to be screed into the car, zip ties etc can mount the amps somewhere.

If possible, I would suggest visiting your local car audio stores to see what they have, some looks great on the companies website and are horrible to use.
