I bought a car 6 months ago and it came with some annoying yellow glue on the plastic.

I've tried baby wipes, not expecting them to work, and they failed miserably.

It seems solid.

Any suggestions?

Perhaps use the Fastest acting yellow glue remover on the market 
OR try:
  Nail Polish Remover
    Petroleum Jelly
    Toothpaste
    Hand Lotion
    Hair Spray
    Baby Oil (mineral oil)
    Vinegar (soak cloth, apply then leave for awhile–even overnight)
    Rubbing Alcohol
    Windex
    Baking Soda & Water Paste (just rub in gently then wipe off with a warm wet cloth)
    Lighter Fluid
    Kerosene
    WD-40 (set for 5 minutes)
    Paint Thinner
    Rubber Cement Thinner
    Artgum Erasers / Pencil Erasers
    Peanut Butter
    Vegetable Oil / Olive Oil (set for about 2 hours)
    Margarine
    Cooking Spray
    Mayonnaise (leave set for a few hours or overnight)
    Goo Gone
    Mr. Clean Magic Eraser
    Furniture Polish
    Eucalyptus Oil
    Tea Tree Oil
    Perfume / Aftershave
    PVC Pipe Cleaner
    For surfaces that you’re afraid to damage, try heating the goo with a hair dryer then wiping off (firmly) with a wet warm & soapy cloth.
    Duct Tape (press on goo firmly, life tape up quickly, repeat as needed)
sure there are more
