The Chevrolet dealership wasn't Larry H. Miller's first, but it will soon be his largest. The current Larry Miller Chevrolet is undergoing major construction work that will soon - target date November - make it the largest such Chevy complex west of the Mississippi.

There will be a new showroom, parts department and service area, something those buying one of the new Chevrolets at the Salt Lake 500 New Car Sell-Off will be privileged to use. About 95 percent of the models appearing in the show will be marked below factory invoice.And what they will see at the show is the extended line of Chevys along with two new models.

New models will be the Lumina line of larger vehicles that was introduced this year. The Lumina model is the first four-door versions of the so-called GM10 series. It is the biggest front-wheel-drive Chevy ever.

The Lumina sedan, with standard four-cylinder and optional V6 power, is the first of the Lumina family to appear. It includes four-wheel disc brakes, four-wheel independent suspension, and an impressive array of standard features. Standard equipment includes power steering, split back cloth bench seat, AM/FM stereo with clock, extended range speakers, visor vanity mirrors, intermittent wipers, tinted glass, left-hand remote rear view mirrors and auxiliary lighting.

The small-car slot formerly occupied by the Chevy Nova has been filled by the all-new Prizm. The Prizm, like the acknowledged high-quality Nova, is a joint venture by Chev and Toyota.

The Prizm will feature tinted windows, front door storage pockets, composite halogen headlamps, reclining front bucket seats, rear window defoggers, child-proof rear door latch and lock mechanism and headlamp-on warning tone.

There will, of course, be the more familiar Chevy names in the show, like Corvette, Camaro and Cavalier.

The Corvette remains the best sports car buy on the planet for a number of reason. The hype of Corvette's newest line is the ZR1, the most powerful production sports car in the world with a 32-valve, double overhead cam all-aluminum V8, with six-speed manual transmission. The trans revises first and second gears for quicker off-line acceleration, while overdrive fifth and sixth gears provide excellent fuel economy.

It also has a new suspension option allows the driver to select one of three setting - touring, sport or performance - which provides different shock absorber damping levels.

It also has a low tire pressure warning system option that continuously monitors the air pressure in each road tire while the vehicle is being driven and indicates low tire pressure through the driver information center.

The Camaro will be offered in the hotter IROC-Z series. Like the popular RS series, it will feature the "Pass Key" anti-theft system as standard. A special coded ignition key and a starter interrupt feature that prevents starting the vehicle with anything but the proper key. A built-in time lag forces a two- to three-minute delay between attempts to start the car with an improper key.

The IROC-Z has hotter performance credentials for 1989 with a 5.0-liter V8 with a five-speed transmission. Optional power is provided by the 5.0-liter V8 with Tuned Port Fuel Injection.

Also back is the Beretta, one of the sleekest and best-selling sport coupes on the market. The hotter Beretta appearance begins with new 14-inch styled steel wheels. Interior features include cloth reclining front bucket seats with four-way mechanical adjusters, optional split folding rear seat, full instrumentation with tachometer, power ventilation system and AM/FM stereo radio with seek and scan.

The Cavalier is the first GM vehicle to have the new GM-designed "Self-Aligning Feature" steering wheel that has a unique energy-absorbing hub to help spread the force of the impact and reduce chest injuries in the event of a severe collision.

The Corsica expands the model lineup for 1989 on half of the most popular carlines, offering a hatchback sedan and sophisticated LTZ sedan.
