At one point, I had considered buying this Fiero. My thought at the time was to leave it with the rough body finish, call it the "Grey Ghost", and just use it for fun. Of course, my white Fiero is presentable, so Ixd have had that option.
The rough body does not cooperate with radar detectors. License plates are particularly reflective to compensate for this. COPs also like to use cameras on everything, so I have used angled yellowed plate covers. The yellow came from age, and I just keep it around, because I can honestly say it got old. The cover has other properties that only allow the plate to be viewed from directly behind. So, no driving by my house and scanning my plate.
