The Ford guys have been getting legit 1965/66 titles for new kit Cobras for years... they thought it adds value to have an early title. Well, cheaper to insure and/or get an antique or classic tag for it to avoid annual inspections and emission tests. Here in PA at least. I know a guy who did, using the VIN on his ERA chassis, and ended with a legit titled1965 car!
Generally when you build a "kit car" or "replica", a donor vehicle is used and rebodied, so you use the donor's "identity" to title, register, insure the vehicle...
However in cases where the vehicle is a custom built tubular chassis/uni-body, or no donor vehicle is used, most States allow the vehicle to be titled as the year of production it represents, a State issued VIN is often applied, unless the vehicle is supplied with an MSO#/mfg.VIN which is usually the case with "turnkey" replicas
