Timely like death and taxes (and I will say that the comparison with taxes is starting to feel more and more appropriate) Forza Horizon is going to get a new DLC car pack on January the 1st.
The new downloadable addition, dubbed January Recaro Car Pack, will take 400 Microsoft Points from your virtual wallet and will feature six rides: 2012 Cadillac Escalade ESV, 1983 GMC Vandura G-1500, 2012 Lotus Exige S, 2012 Lexus LFA Nürburgring Edition, 2005 Mercedes-Benz SLR and 1995 Ford Mustang Cobra R.
Those that got the Season Pass will get all the new cars for (relatively speaking) free, and a further bonus ride: the 2009 Pagani Zonda Cinque Roadster.
Personally, the LFA will probably make me give in and get it. The trailer and screenshots below might help you make your own decision.
