I just want my car to be returned to the condition it was in before the crack. Aftermarket glass seems to have some issues. I'm all for an aftermarket hood or trunk strut that does the job as well or better than OEM. Is that even in the same ballpark of staring through a distorted aftermarket windshield on my next 14hr trip to TX 'cause I happened to get a "miss" on a
"hit or miss" aftermarket piece of glass?
Grooms makes great aftermarket engines. Anybody drop one of them in their Lexus lately?
What about these threads?

There are a bunch more. I didn't give any thought to OEM vs. A.M. Until I read some of these. Would I insist on an OEM Hyundai glass for my teenage daughter's Sonata? Heck no! The PPG or Pilkington is probably better. I didn't ask for Genuine GM parts for my Suburban glass last year. One of these two companies probably makes the glass for GM.
I really like the LS430. It deserves the best I can do for it so I'm shelling out the bigger bucks just like I do for the better/best oil, gas, filters & tires. I might just try some A.M. glass next time 'cause I'm sure the new 'shield is gonna be a rock magnet. Then I'll have firsthand experience. Maybe chow on some crow... Maybe not! Until then I'm going with the OEM.
Here is a little snippet from Autoglassmagazine.net
Is there a difference in quality between OEM and non-OEM windshields? Are ever-shrinking profits and insurance mandates forcing auto-glass shop owners and operators to choose parts purely based on price? How much does a quality installation count toward making any replacement windshield fit properly and protect drivers and passengers?
Don Howig, owner of Ziebart Speedy Auto Glass in Jamestown, N.Y., refuses to debate. "We use OEM glass because we can depend on the fit for a given vehicle," Howig says. "We've tried a couple of windshields from another company [whose executives] told us that with their new manufacturing equipment their products were just as good and less expensive as our OEM glass. Our experience turned out to be otherwise. I don't like creating problems for myself, so when I know something works, I am more apt to stay with it, even though the cost is slightly more."

Replacement parts from OEM suppliers were found to be better, according to a 5-year-old study comparing replacement glass made by OEMs with replacement glass made by domestic and foreign vendors who were not supplying automakers directly. The automotive glass quality assurance department of PPG Industries Inc. in Pittsburgh, conducted the study. The researchers found that automotive-replacement glass made by OEMs fit closer to original equipment, resembled original equipment, met the safety standards as original equipment, had the same high-optical quality as original equipment and was easier to install. This type of replacement glass also reduced wind noise and leakage problems because of its tight fit, PPG officials say.
These guys know a whole bunch more about glass than I ever will.
