I've been a fan of these replicas for a long time. The trick is to get one with reinforcements welded into the chassis before the assembly. It makes a huge difference on handling, making it even better than the now ridiculously expensive original which comes with its original structural flaws.
Another thing I've seen which makes me laugh is how much snobbery there is on these replica cars "you have a fake Porsche", "doesn't it bother you that you're fooling everyone into thinking it's the real thing?". Meanwhile they only drive their original cars like the little old lady from Pasadena on days with 110% perfect weather because the car is now the equivalent of a baseball card on wheels.
This was kind of a cool idea, although I would have gone with much smaller wheels.
Here's an original allegedly owned by the Piech's.
