39 | Purpose | Weekend car. Mostly street and some strip. |
40 | Comments | More fun than it should be. There's plenty of low end torque and it pulls well into the higher RPM range. The Berg 5 tranny truly makes it a street racer with the ability to cruise the interstates at 70mph all day long. When "on" it i get fuel milage in the mid teens, but cruising on the interstate it gets 28mpg. The car is a sleeper in that the exterior is totally stock, even down to the large late model bumpers. It really suprises the V8 boys. For more info take a look at http://www.glenn-ring.com/resto/ . |
