1969 Mercury Cougar XR-7 Convertible - 428 Cobra Jet Ram Air - 1 of 96.

It took a while, but Mercury finally got the message in 1969: the Cougar deserved a convertible, so the refreshed lineup, which also landed with a massive overhaul, included a new body style with a hinged glass rear window.
The Cougar convertible rapidly caught everybody's attention, but not all customers could afford it. The convertible was the most expensive model in the lineup, carrying a price tag of $3,575 for the XR-7/ The base Cougar could be had for $2,999 when ordered in the base hardtop version.
As if the convertible body style wasn't enough to turn this Cougar XR-7 into a head-turning machine, the car also hides massive power under the hood.
The base engine on the Cougar was the 351 with 250 horsepower, but Mercury also offered several more potent options, including a four-barrel version of the same unit. It produced 290 horsepower.
The company discontinued the 390 V8 two-barrel and offered only a four-barrel version with 320 horsepower, but the icing on the cake was the 428. The Cobra Jet developed 335 horsepower, but customers could also order the Super Cobra Jet with a Ram Air intake, producing 400 horsepower.
Only 394 Cougars rolled off the assembly lines with this paint code, and only 110 used the same paint and trim combination. Only 127 Cougars left the factory with Ram Air induction, but more importantly, this convertible is one of only 96 examples with the same engine and transmission.
The photos confirm it's a showstopper, but buyers must know this convertible comes with several modifications, including reproduction 15-inch aluminum wheels, LED tail-lamps, a restored steering wheel, and an upgraded air conditioning system.

The owner will let it go for $169K on eBay.
