I think the G looks better without them, plus they are so low on the door I don't think they'll do much good.
Problem is they were on the car when I bought it (used) and I'm sure they were installed when the car was new and it is a black car. Any ideas on how to remove them and not have bad shaddows on the car?

 

Few coats of wax should do the trick...I removed mine also and didn't have any shadow marks but my car was only 4 months old.

 

Assuming you have a coupe??

If coupe no problem.
If sedan, there are mounting holes in the body behind the strips.

 

i removed mine after having them on for 2 years. I didnt notice any discoloration at all. The task was painful tho as i didnt have the right chemicals to use. Goo gone didnt work for crap. I ended up using 3m general adhesive remover. If you don't have that, good luck!!
