Both a Lamborghini and Ferrari, Sorry Dude, I don't.... Dogbreath may be...
but the thing is if you going to have a lamborghini and a Ferrari, then you might like to choose two compelely different style, such as, if you have a Roadster, you might not like to chose a Spyder, if you have a Coupe you might want a convertible...
Like your Lamborghini VT Coupe, i suggest to get a 550 Spyder, Berchello or something like that... its a different feeling of Driving experience from the Lambo (front Engine, RWD), where the Lambo is a Mid engine 4WD, its converable, and prestige. the service is pretty much the same as a Modena any way
