Yes they are legit. They were on my delivery route when I drove parts for the acura dealership. Although they are legit, they also suck. I know plenty of people who have had problems with them. One of my best buddies took his delslo in there for a kit and hood, and they seriously ****ed it up, and then ripped him off.

If you find something brand-name and packaged by the manufacturer and for a good price, its probably safe to buy it from them and install it yourself or locally. But considering my experience (living near denver, I know a few peeps that have been there), I doubt they'd have the best prices on anything.
