The trouble is, as I see it, is the difference is between a collector and a horder. I would love to have kept all the cars that touched my heart or represented a significant period but had I done that then their replacements wouldn't have appeared. Plus there are some I still have an itch for. GS for one. I see a black one around Dorset often and every time I think...must get one of those. I also think a well sorted Brera V6 in black with tan hide would tick a box. Never fancied a lambo apart from the Espada and I'm bl00dy glad I didn't scratch that itch.
4 or 5 is about it then they can all be used regularly.
