I think overall I am more a fan of the spun wheel, probably because they were introduced about the time I was entrusted to buy my own Dinkys with pocket money rather than get them as presents. I lusted after the cadillac 131, but even shop soiled without a box couldn't afford one (settling for a similar condition Capstan van instead - probably worth more now!).
As former Sec of the Woodie Car Club, I attach a photo of my Plymouth Estate cars. The Meccano one is built to contemporary Meccano plans but unlike the Dinky has the embellishment of a rear mounted spare.
