Vehicle Highlights

This upscale version of the Ford Five Hundred was the first Mercury car in over a decade to offer all-wheel drive. Montego came in Luxury and Premier models with a 203-hp 3.0-liter V6. Both offered front-wheel drive with 6-speed automatic transmission or AWD with a continuously variable automatic transmission. A CVT provides variable drive ratios vs. a conventional automatic's fixed-ratio gears. All Montegos had antilock 4-wheel disc brakes and traction control, but no antiskid system was available. Luxury models came on 17-inch wheels, Premiers on 18s. An optional Safety Package bundled front torso side airbags with curtain side airbags designed to deploy in rollovers as well as in side impacts. The Montego and Five Hundred shared a platform originated by Ford-owned Volvo, plus a five-passenger design with seats mounted about 4 inches higher than in other cars. A power driver seat, fold-flat front-passenger seat, and split folding rear seatbacks were standard. Leather upholstery was standard on Premier, optional on Luxury. All models came with xenon headlamps and LED taillamps. Options included a sunroof and rear obstacle detection. Montego performance and accommodations mirrored those of comparably equipped Five Hundreds.

Consumer Guide® Road-Test Evaluation

The Montego's acceleration is adequate and on par with most V6 rivals, even though it has one of the smallest engines in its class. A test front-drive Mercury Montego did 0-60 mph in 7.9 seconds; a test AWD Ford Five Hundred did 7.5. The CVT's best trait is good highway-passing response, though some drivers may need time to adjust to its behavior in rapid acceleration, where the engine speed can race ahead of road speed until CVT reaches the "right" ratio. Disappointingly, the 6-speed automatic hunts between gears, particularly in hilly terrain, and includes neither a manual-shift feature nor the capability to lock out the top three gears. A front-wheel-drive Mercury Montego with 6-speed automatic averaged 15.9 mpg in a test that included gas-eating acceleration runs. A test AWD Ford Five Hundred averaged 19.1 mpg in a mix of city/highway driving. Mercury recommended regular-grade fuel. The Montego's ride is generally absorbent and composed on all surfaces, though the sharpest bumps can jolt. There is little difference in ride quality between the available 17- and 18-inch tires, or between front-drive and AWD. The Montego exhibits good balance in turns, with only moderate lean despite its relatively tall body. Steering feel is light at low speeds for easy parking, and becomes satisfyingly linear at higher speeds. Test AWD Montegos furnished outstanding grip on wet and snowy surfaces. Both brake-pedal feel and stopping power are good. Inside, the Montego's gauges are clearly marked and unobstructed, though some testers say the electronic display for audio, climate, and vehicle-information settings is not easy to read. Some audio/climate controls are mounted too low, requiring a long look from the road to adjust. Some testers complain that the stalks for the windshield wipers and turn signals are too far from the steering wheel. The most frequently touched surfaces are padded, but the ambiance is simple rather than elegant. Overall, Montego is reasonably quiet, with fine suppression of wind and road noise. However, the AWD test versions' powertrain whined audibly in even modest acceleration, and the 6-speed automatic transmission's frequent downshifts means the engine roars more often than with the CVT. Up front, the commanding driving position is aided by the low cowl, tall windows, and standard height-adjustable seat. Head room is ample and leg room is fine, though the tallest drivers may wish for more rearward seat travel. The front seats are comfortably supportive, and their high mounting eases entry/exit. Visibility to the rear corners is unusually good. The rear seat area has sofa-high seating with limousinelike leg room and generous head room. Three adults fit shoulder to shoulder. Rear ingress and egress is easy. The Montego's voluminous trunk can hold eight full-size golf bags. Strut-type trunklid hinges don't rob space or threaten cargo. The rear seats fold, but the pass-through is restricted at the bottom by angled side supports. The fold-flat front-passenger seat is useful for hauling long items. The covered dashtop bin is handy, but interior storage is nothing special.
Value for the Money
The Montego earns high marks for its generous passenger and cargo space, a take-charge driving position, good road manners, and available all-wheel drive. Engine choice is limited to a single V6, but it has adequate power for this duty. And while the transmissions have some quirks, they're not deal-breakers.

Each vehicle report contains one rating chart for representative model. Consumer Guide® rates in ten key areas: Performance, Fuel Economy, Ride Comfort, Steering and Handling, Interior Noise, Controls and Materials, Driver Room, Passenger Room, Cargo Capacity, and Insurance Costs. These ratings compare the particular vehicle rated to ALL other vehicles, not a vehicle's standing in a particular class. In the ratings table, "1" is the lowest rating and "10" is the highest rating.
Our reliability study for this generation Mercury Montego/Sable includes details on average repair costs, manufacturer recalls, and everything you need to know to gauge the long-term reliability of this generation Mercury Montego/Sable .

Trouble Spots

Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.

Audio system: The CD player (MP3 capable units only) may skip, hang or otherwise malfunction, but an improved radio/audio unit is available. (2005)

Brake noise: Noise or roughness from the rear brakes is caused by rust on the brake rotors, requiring refinishing and installation of updated pads. (2005)

Brakes: Rear brakes may drag after being parked for an extended period requiring improved brake pads. (2005-07)

Cold-starting problems: The engine may be slow to start (long cranking time) in cold weather, requiring reprogramming the PCM. (2005-06)

Fuel door: The gas cap may be hard to close, but there is a revised cap whose tether must be relocated. (2005)

None: The fuel tank may be slow to fill and the nozzle may repeatedly shut off due to a filler pipe with a bend that is too tight. (2005-06)

Suspension noise: Noise from the rear suspension in cold weather (below 15 degrees F) requires revised shock absorbers. (2005-06)

Vehicle noise: Whining or buzzing from the speakers is caused by the electric fuel pump in the tank, requiring installation of an RFI (radio frequency interference) filter in the circuit. (2002-03)

This chart details a range of prices in year-by-year listings for vehicles in three condition levels:
Good: a clean low-mileage, solid-running vehicle that needs little or no repair.
Average: a car with normal miles on the odometer, perhaps a few scrapes or dings; engine might need a minor repair or two, but runs acceptably well.
Poor: might have potentially dangerous problems with the engine and/or body, or abnormally high mileage; definitely in need of mechanical attention. Valuations reflect wholesale prices paid by dealers at auction, and retail prices on used-car lots. Each range covers all trim levels and engine types for a vehicle with a typical amount of equipment--usually an automatic transmission, air conditioning, stereo, etc. Fully loaded vehicles may cost more. Average mileage is 12,000 miles per year. Keep in mind that these are guidelines only. Actual selling prices vary- especially from region to region.

NHTSA Crash-Test Results

Test 2005 Montego
Front Impact, Driver 5
Front Impact, Passenger 5

The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Sideimpact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
