Thanks Casey. So it is the Sunny kit, which I've never had (or even looked over closely), so I was not aware of the shortcomings of.
If I could find a Revell '62 kit at a good price, it'd be worthwhile and less expensive then buying a number of aftermarket sets to get suitable tires & wheels, better engine parts, etc. + the kit decal looks to be quite nice with clear instrument faces, accessory decals, etc.
