But..... You have a very rare car (the pre-92 ETCs are hard to come by), and getting rid of it to eventually be trashed, and then junked would be a waste...... besides, you can save up money, and then get another car, and keep this one!!! You might as well keep it till it dies, since the resale would be less than its value to you!!!
If you dont wanna spend the money (ie you're going to get rid of your car within the next few years), i would suggest going to walmart and getting the cling type...... You just cut it out and stick it on..... Maybe 2 rolls @ $15 a piece, and you have tintage!!! If you do it right, it looks as good as professional tint!!!
