Question

buddy of mine put these on his yellow car. matter of fact, i ordered them for him off ebay for about that price. he drove his daily and after about 4/5 months of that, they still seemed to be holding up. since then, the car is sold

have alot of patience and a blow dryer
 
Yes they will hold up good. The vinal stickers are very durable. I've had my black reflective on for over 3 years, no pealing or starting to come off at all. Prep is the key to good longevity.

+1 especially on the prep part... make sure the area is thoroughly clean... what i did first was wash the whole car... then went to work on the rear bumper... use a soapy water solution and apply... i got them off of one of the vendors here for like... $14, maybe 15 with shipping
