With the roar of engines, the smell of funnel cakes and the irony of having the Crown Royal sponsor booth within staggering distance of the DUI awareness display, Pittsburgh's 26th Vintage Grand Prix entered its final weekend today.

Cars in uncountable numbers, indeterminate ages and sometimes incomprehensible shapes stretched across the fairways and byways of Schenley Park.

The 2-1/3 mile street course with its 22 turns was the scene of qualifying heats yesterday, with an estimated $10 million in vintage racers buzzing the track that winds through the park.

On the golf course, cars of all prices spread out for display. Thirty antique auto clubs from around the country joined in yesterday's show.

Addison Lynch, 71, of Dormont, greeted folks at his 1949 Packard. It was big enough for a wedding reception.

"Some people call it the bathtub model," Mr. Lynch said of his antique auto which, with its lumpy curves and rounded ends, resembled one of those Buddy L toy cars from the 1940s. Others, of course, think it looks like a large black bathtub.

The thing is powered by a straight eight-cylinder engine, and sports the classic Packard silver swan hood ornament.

"I've had it out as far as Bedford," he said.

Across the lawn from the Packard, Frank Druzisky and Ron George were showing off their Studebakers -- a car that, in their youths, nobody really thought of showing off.

"They were sort of a ho-hum car. They weren't very fancy," said Mr. George.

"They were way ahead of their time," added Mr. Druzisky.

Each man says his car, which originally sold for $3,000 to $6,000, is now easily worth $25,000 or more.

Amid the day's heat, some took refuge in the air conditioning of the Pennsylvania DUI Association trailer, where Dan Shogor let visitors simulate driving under various conditions on a computer-powered dashboard.

There was driving in good weather - a relative cinch. There was driving at night - a bit trickier. Driving in the rain was, of course, slick. Then Mr. Shogor clicked on the computer program to simulate driving after one drink, then two, then three.

Amy Wallisch, 18, of Scott, didn't make it far. After Mr. Shogor entere done drink into the computer, she spun out on a four-lane and crashed.

"Did you guys come down from the Crown Royal booth?" Mr. Shogor asked her.

The Crown Royal booth enjoyed a steady stream of customers who received complimentary cocktails - notably Pepsi and Crown Royal. Everybody was carded, which means the younger visitors were slightly offended and the older ones delighted enough to ask to be carded again.

The good news: none of the drivers had stopped by.

"We sample them after the race," laughed one attendant.

The grand prix continues through tomorrow, and the following road closures are in effect until 6 p.m. Sunday.

-- Schenley Drive will be open to the park at Panther Hollow Road, then closed to the Westinghouse Pond.

-- West Circuit Road will be closed behind the park golf course and to Serpentine Drive.

-- Serpentine Drive will be closed to Bartlett Street.

-- The Boulevard of the Allies will be closed between Greenfield Avenue and the Panther Hollow and Anderson Street bridges.

-- The Anderson Street bridge, where traffic will be forced to bear right onto Overlook Drive.
