Years ago last century when I was a spare parts courier for a dealer, I was given a set of Ferrari wheels to be delivered to a panel shop. Howard told me to "be very careful with them, each one is worth more than your car..." Ouch. These wheels were as light as ? for their size.
Funny; the seller of these wheels on Farcebook is asking $3K for the lot - less than what one new Ferrari wheel was worth back in the day (about $5K each).
