I've seen a couple of Boxsters at auctions with all panels vandalised including deep scratches and multiple dents - well maintained roadsters written off by the insurance company due to our high cost of panel repairs. In Australia at least, you could get one of these for under AU$15k and another AU$20k for the body compares well with our prices of AU$25-40k for a Boxster.
I see two markets for these cars - people who enjoy building replicas supercars (not that this is a replica), and people looking for the cheapest possible way to make their ex-wife lose her mind, and she would. [emoji23]
I love it, although 30% cheaper would be good.
