THIS wailing time machine is blurring me backwards through the decades.

It was in 1990 that I first drove a BMW M car and now, almost 30 years later, I’m back behind the wheel of an E34 M5.

The Daytona Violet example is part of the BMW Classic collection. With a bunch of other pre-M Motorsport and old-time M cars, it’s been delivered to the Kempinski Hotel at Berchtesgaden for a group of Australian journalists to drive back from the Bavarian Alps to Munich.

The vivid impression that my first M car made has endured.

Mainly because of a drive at often hugely illegal speeds (I’m counting on the statute of limitations applying here) from Bathurst to the outskirts of Sydney and back.

There have been plenty more memorable M5 moments between then and now. The power-steering pump of a 4.9-litre V8 E39 failing while I was doing performance testing at Eastern Creek in the late ’90s. Doing repeated launch-control runs in a 5.0-litre V10 E60 on an airstrip in Germany at that great car’s international launch in 2005. Seeing the traction control light flashing at north of 160km/h on a lumpy Spanish road in a twin-turbo 4.4-litre V8 F10 back in 2011.

The most recent memory is from 2017. I half spun a prototype of the forthcoming F90, the first all-wheel-drive M5, on BMW’s Miramas proving ground in the south of France.

In my defence, I was in the car’s ESC-off rear-drive mode and chasing BMW works driver Timo Glock in an M4 GTS at the time. He saw it all in his rear-view mirror.

“You almost caught it,” he told me, laughing.

The old car’s exhaust makes real music, the manual gearbox is a well-oiled pleasure to use, the interior is plain but purposeful.

But the E34 does feel awfully slow, even though this is a 1992 car with the later 250kW 3.8-litre version of the BMW Motorsport-derived in-line six, not the 232kW 3.5-litre engine I remember.

I’d climbed into the E34 expecting a heartwarming encounter with an old, fondly remembered acquaintance, and I got it.

What I hadn’t anticipated was a coldhearted reminder of how much progress has happened in the last three decades.

I’m starting to think that nostalgia ain’t what it used to be.
