If a Dodge Viper was to ever put on a very expensive, tailored Italian suit, this is what it would end up looking like. This Alfa Romeo-badged Zagato TZ3 Stradale is based on the Viper, powered by the ACR’s mighty 640 HP 8.4-liter V10 engine.

The car is currently for sale at TSG Autohaus in Costa Mesa, CA, and the asking price is $699,000. The styling is pretty unique, with the Viper-like side exhaust tips being among the few features that don’t seem particularly bespoke. Otherwise, there’s the “Kammback” rear end, the “double bubble” roof and round taillights, all of which scream Zagato.

This TZ3 is chassis #7 of 9 and according to the ad it has “spent its entire life since returning from Milano in 2013, in Southern California […]”

“This is your opportunity to own one of the rarest cars on the planet. For the collector desiring to tuck it away as a beautiful showpiece or drive it like only an ACR can be driven, it makes a wonderful addition to any collection,” added the seller.

We also showed you what chassis #6 of 9 looked like a couple of months ago. That one had a dark red exterior but a similar black and brown leather cabin – whereas this one features a brown metallic exterior and a Chestnut interior.

Aside from the previously-mentioned 640 HP, the TZ3 Stradale’s V10 engine also pumps out 585 lb-ft (793 Nm) of torque, and in this case, the power unit has only been firing for a total of 525 miles (845 km).
