General information

This page is mostly for the purpose of giving information to those people who want just a little information about these cars. First thing to know is that they were manufactured in the '60s and '70s, by a company called Fiberfab, and later by a company called Classic Motor Carriages. There were 3 basic models, the Avenger GT-12, the Avenger GT-15, and the Valkyrie. The GT-12 was designed to rebody a Volkswagen Beetle or Karmann Ghia. The GT-15 had a manufactured chassis made to accept Chevrolet Corvair drivetrain and suspension, and the Valkyrie had it's chassis designed for carrying a V8 in midship position (just behind the passenger compartment under the rear window. Valkyries were made as both kits and turnkey complete cars. Most Valkyries made use of a Corvair transmission and differential (transaxle) and either a Ford or Chevy V8s, some have ZFG 5 speed transaxles. All models had a later version designated with an X, e.g. Avenger GT-12X. The X models had minor body differences, most notably a chin spoiler.

The GT-12 is the most common. Originally one could take a VW Beetle, and a $700 GT-12 rebody kit, and with quite a bit of work and some money spent on hardware, custom exhaust, gauges etc, and end up with a great looking sports car. The GT-12 weighed about 500 pounds less than the Beetle. The lowered weight and improved aerodynamics boosted the fuel mileage and performance.  The weight reduction was equivalent to adding approximately  30% more power. In other words if you had started with a 40 horsepower Beetle,  your Avenger would run like a Beetle would with 52 horsepower. Of course the lower weight and center of gravity, meant it would out corner and out stop a Beetle as well.

The GT-15 utilized Corvair running gear, which made it about 225 pounds heavier I estimate. Corvair engines came from the factory with 80 to 180 horsepower. Comparing the 180 H.P. version with the V.W. again, this would be like driving a Beetle with 208 H.P., more than 5 times the power to weight ratio of a stock 40 H.P. Beetle.

One Valkyrie have been remade into a street driveable racecar   with  720 H.P. , one can only imagine what that must be like.

Many people who have these cars, especially when they are trying to sell them, refer to them as GT40 replicas. They are not GT40 replicas, anyone who knows what a GT40 (a successful race car with some versions for the street produced) looks like, will not mistake the GT-12, GT-15, or Valkyrie for one, there are many, many differences. However, it is also very clear that the styling of this cars was inspired or influenced by the GT40.

An original GT40 can be had for a bit of change. #1140 was offered for $425,000 ----> 1140.jpg (20093 bytes)

<----1139 Was offered for $950,000

There are kits and turnkey cars which are properly called GT40 replicas. One example is the ERA GT40. This is a real quality kit, for about $55,000.

Not everyone has this kind of money to devote to a car, especially one as impractical as a Ford GT or replica. The lack of head room, luggage space and other things we take for granted in our daily drivers, means that for most people, a car like this amounts to nothing more than an unusual (maybe exotic is a better word) hobby.

Well, the enduring interest in these beautiful cars didn't escaped Fords notice.  Ford spent a lot of time teasing automotive enthusiasts with their concept car, sort of a consumer GT40 for the 21st century. It finally became  available in 2004. They have already ceased manufacturing them. Then can generally be had in the $130,000 to $180,000 range, depending on condition and mileage, and whether they have benn previously owned.  Here is what they will look like:

This is where the appeal of the Avengers and Valkyries comes in. Incomplete project cars sometimes go for under one thousand dollars, while very nice Valkyries are almost always under $15,000. These cars can be made to look great and run great, and can be as sophisticated and exotic as ones budget and ingenuity allows. Each car seems to be different from all others, reflecting the tastes and talents of the individuals who have owned it.

GT40 kits are for the purists, but those of us who like to add individual touches to our cars, prefer to tinker with these low cost toys. This kind of tinkering with a GT40 or GT40 replica, diminishes it's value. It is a nice feeling to drive our Valkyries and Avengers, turning heads like you cannot believe, and being satisfied that we have considerably less money in our cars that the kid down the street with the Honda and bolt on spoiler.

So, what are the cars like, what are the specifications? First let me make it known to you, that if you want to look at examples of Avengers and Valkyries, you should visit our galleries. If you want to find a car for sale or see what they go for in general, you should visit our showroom.

Well, history has a way of repeating itself. A new company has recently been formed. This company began producing Valkyries for the 2004 Model year. It is not affiliated with the Fiberfab management of the past, but the Valkyrie will be reproduced under the new Fiberfab.
