What do you think about fake convertible tops? It looks cool – American taste, right? – or is it a little over the top?
I came across this Cadillac Seville on display outside a car dealership in Drøbak. The car is a 1995 model Seville of the 4th generation with a transversely mounted 4.6 liter Northstar V8 engine. The latest models of Seville are stylish cars with a design that has held up well. What caught my interest was the vinyl roof. This is a special type that is retrofitted to new and used cars in the USA. There the solution is called carriage vinyl tops, with an allusion to earlier horse-drawn carriages. In any case, the tops look like real, foldable canopies. That is why they are also referred to as fake convertible tops.

Vinyl roofs come in many forms
The purpose of vinyl roofs is to give the cars more character as convertibles with retractable roofs. You can find cars with vinyl roofs all the way back to the 1920s, but it didn't become common until the 1960s – especially the latter half when vinyl roofs became an optional extra on very common car models. They were often expensive equipment variants.
The vinyl fabric was glued to the roof with the ends hidden within the front and rear window moldings, as well as chrome moldings along the sides. Vinyl roofs could also be retrofitted. A solution that became quite popular in the 1970s was vinyl roof on box. A substance was simply sprayed onto the roof that gave the same surface as a vinyl roof. This solution was often used after body damage to repair car roofs.

Landau roof
In the 1980s, vinyl roofs disappeared as an option on European and Japanese cars. In the United States, however, new vinyl roofs began to take shape. Landau roofs cover about a quarter of the roof at the rear and are reminiscent of old horse-drawn carriages of the “Landauer” type where you could fold down the rear part of the roof. Some car models with landau roofs even had fake hood handles on the sides – for decoration. You can still buy these as accessories on Ebay.

Only in the US
Let's go back to the Cadillac in the main image. It has a lavish solution that looks like a real convertible. You can tell that there are roof bars underneath and that the side rails cover the side windows like a real convertible. Also notice that the texture is the same type used on real convertibles. It all looks good, even though the roof is not foldable in reality.

Retrofit styling
In the United States, vinyl roof conversions an offer for owners of newer sedan models, such as the Cadillac CTS and Toyota Camry (US). Carriage Tops is not glued directly onto the original roof. It is first built onto a fiberglass shell that is adapted to the car model. The shell is then placed on the car's original roof with rivets and silicone. Finally, the moldings are screwed into place.
Disadvantages of vinyl roofing
Vinyl roofs do not stand the test of time very well. They can crack and moisture can get inside. It is not uncommon to find rust damage under old vinyl roofs. When vintage cars undergo full restoration, the vinyl roofs therefore disappear. However, many have experienced that the underside of factory-installed vinyl and landau roofs is poorly finished by the factory. Removing a carriage top with a fiberglass shell, will leave damage from fasteners. This type of roof also has another disadvantage. If you are unfortunate enough to have the rear window broken, you may risk having to remove the entire fiberglass shell first.
But why remove the vinyl roof? Doesn't it give the car more character?
A Cadillac will never be a common sight in Norway. With fake convertible top becomes even more interesting, – but not necessarily more beautiful. One might add that it represents American taste more than European. The car in the main picture can therefore be described as a small piece of America in Norway. Here, all “closet Americans” can put on plaid pants, Hawaiian shirts, baseball caps and let the tones of Merle Haggard roll out of the player.
