I love these little replica cars because I love the style of the original cars. We can drive the wheels off of our replica cars where most if not all of us would never drive a fully restored original Speedster. So badge them or not, your choice. I have yet to be pulled over by the trademark police, but who knows? In the mean time, I am enjoying the heck out of my recently finished Speedster Replica. I drove it to work and back in 30 degree weather today thanks to the Subaru water cooled engine and heat setup. Should I replace the Porsche emblem with a Subaru emblem?
