I have a 1969 Ghia that I have refreshed. Rust free top to bottom, dropped in a modern interior and the engine is a perfect 1,600 dp. It is not a rocket, but its not slow. No slower than an old 356 and it gets just as many looks. Plus it corners like its on rails and is dead-easy to work on. Plus, minor modifications like dual carbs can make them pretty quick.
Its way roomier than my Spider 124 and its a rock-solid reliable daily driver.
I drive it to Seattle from time to time. 75 MPH over the pass, passing many modern cars.
The Ghia is a gem. Love it.
