I like to trade those for some standart race cars, like rally cars or those tunned like the red celica or 350 option stream Z, or the oreca viper, preferible that kind of car.
I have
Lancia Stratos rally car '77
Honda Loctite Mugen NSX '01
Ford GT LM Race Car Spec II
Nissan Calsonic Skyline GT-R Race Car '93
Lancia Delta S4 Rally Car '85
All untouched, willing to trade any one of these for the Jaguar XJ13

Ok, when you decide which you'd like for the Jag, you can email me at f1p1trade@gmail.com, I check often on my phone, as I'll be at work myself in about 7 hours from now. If you decide before then, let me know. Otherwise, I'll keep checking the email. Thanks.
