Heck, last year, I think I only bought one model, and it was a 1:43 of a car I wasn't even really looking for!
Just not that many must have cars for me left but a handful that the manufacturers just seem to forever ignore for some reason. Heck I can happily end my acquisitions with the following:
1970 Alfa 33/3 LM long tail spyder
1969 LM Porshe 908 LH
Lancia D50 with the pontoon tanks
Lancia D24 spyder
Voisin Aerodyne Sport
......and that's it!
Sure quite interesting models like the recently posted AU race car transporter comes up and piques my interest, but in the end I just can't justify such models that will just take too much space and I would never really like with a passion like most of the classic race cars I already have in my collection.
