Of course I read the description, although, I couldn't see where it said where or how it was purchased so it could of been a cheap knock off from the internet. I bought a pair of Ray Bans in Thailand for a few pounds, they must have been real because the guy said so and it says Ray Ban on the lenses.
Known and reputable brands have spent a lot of money in R&D into their products for a reason, hence their price. Whereas cheap unknown eBay kits are knocked up in China with no testing for minimal cost and maximum profit. I really hope we don't see a blown engine/turbo post from you.
As other members have said, these are cars you shouldn't really be cutting corners with and going for cheap. Just trying to look out for a fellow member that's all...
