You'll enjoy that, it's a strange experience as in normal driving it's very docile, to me felt no different to an IS250. Then get it over about 3.5k revs and it goes insane, the engine sounds incredible!
I believe there's only 1 LFA around so can obviously only be in one place at one time, but assuming there's only 1 open road per day they must be moving it from one location to the next.
My invite says refreshments will be provided all day so there will be something available, have booked in for drives of the CT, GS and LS but not too fussed about those to be honest, more interested in hearing the LFAs glorious V10 so hoping I'll have the time to pop in for at least a short while :)
