Those old kits certainly pose a challenge, but with a bit of work can make up into nice little replicas. I can remember the old bagged kits from
Airfix from way back in the 50's and 60's. There were other manufacturers who made 1/32 scale auto kits from way back.
Revell had a small series I think named Highway Pioneers, whilst Gowland and Aurora had 1/32nd scale ranges as well. 1/32 scale seems to have waned over the years except in the slot car racing field.
Airfix made nice little Bugatti T35, MG Magnette and Alfa Romeo kits in the 70's and still persist to this day making a limited number of car kits in this scale.
I agree with Dave about some of these bagged kits being sold for silly money by traders, considering that many of these kits were poor anyway. A few years ago at SMW Telford I spotted a Mk 1 Vauxhall Viva on a traders stand that interested me as I passed my test in one. The asking price was £50.00! I may have passed my test in one but also passed on the kit at that ridiculous price. Would not mind betting the trader picked it up as part of a bereaved modellers collection for next to nothing!
