If ever there was an American sedan that combined traditional full-size accouterments with European style and class, it is this edition of the Bonneville. Introduced in 1992, the Bonny competes with roomy offerings such as the Ford Taurus and Toyota Avalon, but kills the competition with full-sized seating for six, attractive styling and unusually good performance capabilities for a big, front-drive four-door.

The Bonneville benefits from a powerful base engine; a 3800 Series II V6 that pumps out 205 horsepower and gets an amazing 29 miles per gallon on the highway. Optional is a 240-horsepower supercharged variant of the base V6. If you must have the supercharged engine you have no choice but to accept the goofy aero add-ons and wizardly doo-dads that come standard on the SSEi. Pontiac no longer offers the blown motor on the base Bonneville.

The base model is the SE, which includes a rear decklid spoiler for 1998. Next up is the SSE, which is basically a sporty version of the SE. The SSEi is a package available on the SSE that includes the supercharged engine and flashy trim. Last year, buyers could build a thoroughly competent supercharged sport sedan using the SE equipped with the SLE option package. This year, the only way to get added speed and power is to pop for the top-line trim level, with all of its unnecessary gee-gaws and myriad power seat adjustment buttons.

Otherwise, Pontiac carries the Bonneville over nearly intact for 1998. SSE models gain an eight-speaker Bose sound system and the Head-Up Display as standard equipment, and second-generation airbags (a.k.a., de-powered airbags) are standard. Camel is a new interior color, and exterior paints come in fresh hues of blue, green and gold.

The Bonneville continues to provide excellent value for your full-size car dollars. If the Ford Taurus and Dodge Intrepid are a bit too loud for your tastes, the Euro-chic Bonneville SE should meet your requirements for a large, stylish and speedy sedan.

1998 Highlights

Second-generation airbags are standard, the SE comes with a standard deck lid spoiler, and the SSE gets more standard equipment. New colors freshen the aging Bonneville.

Bought this used, with clean CarFax and low miles. Put few miles on per year, and keep up with routine maintenance. Thank God I got an extended warranty. Thousands in repairs of all sorts in the 4 year warranty period, including a replaced engine - which lasted 5500 miles before the 3rd engine. Add'l items not covered by warranty, like sunroof, gauges, fuel lines, starter, and on.

Warning!

VincentModrak,03/17/2008

I bought this car a year ago off my Dad and ever since it has been a nightmare. Shutting off randomly at first. Then the water pump blew out in October, $300. One month later my Upper Intake Manifold cracked for a second time in 3 years flooding the engine with coolant causing my starter to blow as well when trying to restart. The Upper Intake Manifolds on these cars are made of cheap

Great Car! I love my Bonneville

1998bonnie,07/05/2013

I purchased my 1998 Bonneville SE in 2004 with 76,000 on it, now it has over 143,000. Being that it was sitting on a Chicago used car lot for I don't know how long, I didn't know if it was a good deal or not buying through Ebay. After I got it, I have several things done to it. It's still a good over all great car. In 2011 I had the anti-freeze problem fix with gaskets replaced, upper

Run away from Bonneville & GM

Nomorbonnevilles,05/08/2002

I purchase my Bonneville SSE new in 1998. At $56,000 the plastic intake manifold cracked, allowing fluid into the cylinders which locked down the engine. Now at 102,000 miles the same thing. No help from GM either time. I am out over $2000 for this poor engineering design. The more I look into it, this is a very common problem with this engine. From day one, the

Should I lease or buy a 1998 Pontiac Bonneville?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
