I have registered 2 Speedsters and 1 Spyder in Texas. It is always a shot in the dark when you go to the license branch....the first Speedster I made 4 trips to the license branch, I had an MSO for the chassis, a VW title, bills of sale, an inspection completed by a representative of the state police, etc etc.....on the 4th visit I had an entirely different person than the last 3 visits, she looked at the MSO and the bill of sale, and approved the entire mess without looking at anything else at all. I had title application done in about 3 minutes after having spent litterally hours previously.
On the second Speedster it was previously titled as a 57 VW Convertible, so that is what it stayed.
The Spyder was a new build, I originally submitted it as "Porsche Spyder, 1955, Replica". It came back to me as a Porsche Spyder, 1955. It is licensed as a Porsche Coupe, 1955. When I enquired "why" on both points the best explaination I got was the manual did not cover anything but a coupe in 1955 and that was the "best" way to license the car. As to the title, the car did have a 1955 pre "A" 356 Porsche engine in it when I first titled it and according to the title people, they indicate it can be titled as to "what it looks like" legally....as long as it is not represented to be "original" as to resale....and the engine was sufficent to title it also.
All these 3 storys really have to say is the law is not understood, may be enforced differently, or may be un-enforced, depending upon the dilligence of the clerk, how they read the statutes, and what mood they are in.
I am not compfortable that any one of these 3 cars is or was ever correctly titled or licensed. I have read the various statues on more than one ocassion, and I can't clearly say what should be done... however, my insurance company is happy, the inspection station is happy, the local law enforcement people are happy, the state of Texas got their legal sale taxes, and the cars are all on the road...so I am happy too....
Just don't get pushy with the folks at the license branch, make certain you pay the appropriate sales taxes, and try to get it titled under the "looks like" rules, as those may well not require emission inspections....you don't want emission inspections on these things as a modern car, never pass.....the other option may well be licensing as a "collector car" in Texas. By the way, don't confuse title with licensing.....
