If the new Cadillac Escalade isn't imposing enough, you could always take yours to the experts at Rezvani Motors, which will gladly offer you the recently-launched Vengeance armored SUV. You'd never tell but, under all that bulky bodywork, sits the bare bones of an Escalade. The company has now launched a configurator that gives us a look at all the available extras, some of which carry an outlandish price tag.

The base MSRP is $249,000, but this quickly inflates as you chomp through the options list. Up to ten colors and finishes can be selected. Opting for a satin look comes at no extra cost. If you want a gloss finish, that will set you back $5,000 for any shade. The Camouflage option (in satin or gloss) costs $7,500. Should none of these colors take your fancy, Rezvani will paint the Vengeance in any color you like - in return for $10,000.

Sadly, you can't elect to change the wheel design, but the available exterior accessories should take your mind off that.

For $4,500, Rezvani will fit a 12,000-lb winch that's built into the steel front bumper. A roof-mounted LED lightbar is also available for $2,750. Buyers can also specify the Custom Shinedown Logo at $2,000, which projects a unique logo when the front doors are opened.

Inside, Escalade owners will feel right at home, as the Vengeance borrows its plush innards from the Cadillac SUV. Two interior color schemes are offered; Black and Ivory. Both can be paired with your choice of Gloss Black or Brushed Silver trim. If you're looking for wood trim, you're in the wrong place.

Of course, the Rezvani enjoys the Escalade's amenities, meaning there isn't much in the way of options. But for an additional $1,500, a bench seat can be fitted to the middle row, which increases seating capacity to eight. Custom-embroidered seats are also available for $1,500.

But the biggest option has to be the phenomenal Executive Seating Package. For a whopping $125,000 (more than a well-specced Escalade) the cabin can be transformed into something incredible.

Two recliners replace the sensible 7/8-seater configuration, and there's a keen focus on luxury. Of course, these leather-trimmed pews offer heating, ventilation, and massaging functions, as well as a partition to keep the cabin nice and secluded. For your entertainment, you'll find a big-screen television, iPads, and Apple TV. To improve on the ambiance, Rezvani offers buyers a choice of overhead lighting or a Rolls-Royce-style starry night headliner.

A 6.2-liter V8 with 420 horsepower and 460 lb-ft of torque comes as standard but, for an additional $3,000, Rezvani will fit the 277 hp/460 lb-ft 3.0-liter diesel engine. In a vehicle weighing as much as this, these powerplants are a bit mean. Those looking for more muscle will be tempted by the Supercharged 6.2-liter V8. With 682 horses and 653 lb-ft under the hood, it should move the Vengeance about with gusto. It comes at a big price though - $125,000, to be exact.

If you're going to get the mighty supercharged mill, you might as well spring for the $4,500 Sport exhaust.

If you've still got money left in your coffers, the available packages will quickly rectify that. A $95,000 Military Package includes bulletproof glass, body armor, underbody blast protection, a pepper spray dispenser, seven bulletproof vests and helmets, gas masks, and EMP protection.

Other packages include the $3,500 tow package, which enables the towering leviathan to haul up to 8,200 lbs. A night vision system ($8,500), rifle compartment ($4,500), center console safe ($1,000), tire inflation/deflation kit ($3,500), and a solar power system ($2,500) are just some of the available options. Tick all the boxes and you're confronted with an eye-watering price tag of nearly $650,000.

If that makes your wallet groan, perhaps a regular armored Escalade will be better suited to your needs. Still, it's amazing to see what Rezvani can offer its customers, some of whom will almost certainly specify their Vengeance with all the toys.
