Many will disagree but i have never had any problems in Illinois...
i didnt have DMV issues i had title printing issues when i got the 1967 title switched from my grandpas name to my name (67 was when it got switched from my great grandpas name to my grandpas name). I asked my local DMV if there was anyway to get the origional title back for sentemental and historical purposes and they said they couldnt promise anything but with the application they stated the owner wants the origional title back. Well i got it back and they didnt even touch it! so i got my title back along with the current actual title.
now the problem arose when i got the real title back the first time it said it was a 1929 ford grand cherokee....dont even wanna know how that happened as i looked at the handwritten copy copy that was sent off and it clearly states 29 ford model aa...
then good ol il sent a letter saying my 29 ford grand cherokee was deemed more than the $25 tax i already paid and wanted another $972 in taxes!!!
soo my dad and i wrote a letter to them explaining what happened, photocopy of the 67 title, photo copy of the fudged up title, copy of the copy of the application the dmv lady filled out that was correct and send pictures showing its current rusted carcas state. week later another title that was correct showed up and was told to ignore that tax letter haha.
but i have stopped in my local state police station and asked them about legality of me putting flashing amber lights on the back/roof of my truck as there is no way to make it out of my town on a non 55MPH road. mostly highways... he grabbed the shoebox thick vehicle code book and it clearly states snowplows and towtrucks and state vehicles and construction workers are the onlyones allowed to have flashing or rotating lights on and only when they are performing thier task.
he said he personally and none of his fellow officers would give me any grief about having amber flashing lights (i plan to set them up much like IDOT's orange trucks where they flash twice per side and random patterns) and he felt it would be a safety hazard if i didnt have them. i already have an orange triangle on a c clamp to use and plan to put another brake/tail on the pass side.
so really at least in my area the police arent too bad about hassiling classic car owners (as long as you arent speedig, burnouts etc) most of them like to oogle over cars and do show up and wander around cruise ins just to check out cars
