Nice collection there. I recognise a lot of the ones I have
Mine are all still in boxes at the moment as I haven't worked out how I am going to display them.
Out of my collection my favourites are all the F430 variations but in particular the Scuderia, also the blue Veyron and the red and black one from 2003, the FXX in the red or black with striped colour schemes, 250 GTO, 458 Italia in red, the grey Reventon Roadster and both colour Lambo 570 superleggeras
Some of the Garage and Vintage Racing muscle cars with rubber tyres are really nice too
I also have most of the Speed Machines - they're not terribly accurate with those big fat wheels, but in that scale it works, and the extra details and nice colour schemes make them a nice step up from the basic hot wheels.
