Yes, the wire wheels are a weak spot. Not all 1/32 kits are so poor. Airfix, decades ago, came out with Porsche 917s (CanAm racing), the Aston Martin "Ulster" (with opening trunk) and a Bugatti or two.
Re: other things, research into old fotos on line can show little things to detail interiors, like door handles, arm rests, etc. Sometimes steering wheels are too big or small, or just too darn thick and can benefit from trimming. Last, some guys are skilled enuf to print decals of dashboard dials in scale, which helps a lot. Careful brushing of the bezel trim rings with silver and later a dab of clear over the dry decals and they can really add to realism. Thanx for my #2 fave sports car of the '60s, the TR-4A!
