Like with most stuff packs I expected there to be a few bits and pieces that I'd like, and then a few things I would never use. For this reason I waited for the price to come down before I invested in it. And I'm so glad I did. I honestly don't think we can even call this a stuff pack - where exactly is the stuff??
After installing stuff packs I always like to go into "Create a Sim" and see what new hairstyles and outfits there are. Because I do that I can tell you that this stuff pack consists of quite a few jeans, a number of tops and very few outfits (and zero shoes at all!). Although these items are quite nice (with Diesel printed on most, but not all, items) there just aren't enough items. Despite this, the female clothing in particular for young adults is really quite good - a full-length jumpsuit that you can see on the back of the box is especially nice and I really liked that. The Diesel underwear for men is good but for women we are only given one new garment and the same can be said for the swimwear.
Unfortunately, and this was the biggest let down for me, there are no new hairstyles. I was so disappointed by this because I really like to change what my sims look like regularly to mix it up a bit. Aside from this though, there are a couple of nice items in the home design section. I particularly like some of the Living Area items, like sofas and so on; they all seem to be quite modern. This stuff pack certainly focuses much more on the interior design part of our games rather than the sims.
Overall, I am disappointed with how little this stuff pack has to offer. I have to say though that, as this is Diesel, I did expect that there would be more of a focus on clothing (a little on interior design as well) rather than such a small input into clothing and our sims. I can forgive the lack of hairstyles but otherwise, I probably wouldn't recommend this to potential buyers unless you're a die-hard fan (or you can get it nice and cheap!!).
Hopefully EA will make it up to us with the upcoming "Supernatural" and "Seasons" expansion packs. Happy Simming! Hope this helps.
