It never occurred to me just how much DLC Forza Motorsport 4 has. Hell, the entire series has a mountain of DLC. Not that it's a bad thing, I guess I just never thought about it. That Season Pass would have really come in handy. At any rate, the "July Car Pack" is this month's DLC for Forza 4, available today, and it's sure to not disappoint.
In it, you'll find the 2012 Spyker C8 Aileron, 1995 RUF CTR2, 2012 Mercedes-Benz SLK55 AMG, 1956 Lotus Eleven, 1954 Jaguar XK120, 1952 Hudson Hornet, 1998 Aston Martin V8 Vantage V600, 2012 Ascari KZ1R, 1973 AMC Gremlin X, and the 2011 McLaren 59 McLaren GT MP4-12C GT3 (my personal favorite). That McLaren might be worth the price alone. I would do unspeakable things for the real-life counterpart. I've recently been in the market for a new car, after all. I'll just use up a couple of my wheelbarrows of cash for one.
You can download the "July Car Pack" this very second for 560 Microsoft Points, and you can check out the trailer/gallery that shows off the cars if you're not convinced it's worth the cash.
