this is just my 2 cents on this.
Anyone that is purchasing either of these cars is not doing so because they are the "best" honestly every sports car this expensive spends a lot more time under a cover in a garage than it does on the road, a shame, I know. Really both of these cars, SLS and LFA are more a work of art than they are transportation. if you'd like insanely fast transportation a 911 turbo or a GTR will fill that shoe for a lot less. both of those are expensive but nothing like the LFA or the SLS. the LFA, SLS, 458 italia, anything Pagni... Its all car artwork.
And I'll take a Panoz AIV Roadster.
to each their own right?
