This is a pretty wicked car


Leading up to this car, Mike Dietel was importing European-spec BMWs for the west coast market. With a keen eye to create the most dramatic 3 series possible, he envisioned this car which was the last to come from Dietel Enterprises in Laguna Hills, California. Engineer Tom Coleman extensively reworked the entire car including engine, chassis and interior modifications.

The basis for this 345i was the 3.2-liter engine from the 745i with mild forced induction. Turbocharged to 7.5 pounds of boost, 310 to 340 bhp was available which was quite a bit in 1982. Power was sent to the rear wheels through a close-ratio Alpina five-speed transmission
and limited-slip differential. Despite the bulk under the hood, Dietel still found room for the air conditioning system.

To deal with the increased power, Dietel significantly upgraded the chassis with triangulated chrome-moly tubing. Furthermore, the suspension components were upgraded with chrome-moly replacements including Bilstein/Alpina coilovers and drop link front sway bars. Brake rotors from the BMW M1 were also installed with Lockheed Martin 4-piston calipers.

The distinct wide-body kit was a new design which Dietel hoped to market. It was built from fiberglass by Wayne Hartman Fiberglass. The design predated the E30 M3 which effectively replaced this type of car. One major criticism of the design was the American-spec bumpers which were much larger than their European counterparts.

At their 2009 auction, Barrett-Jackson sold the only Dietel 345i for $30,800.00 USD.

$31k for the only one? That's an amazing deal IMO.

I saw that car at the 2006 BMWCCA Octoberfest in Grand Rapids.
I thought I took a few pictures but can't locate them in my Octoberfest 06 folder. I do have pics that I took of the orange 2002 that was built at the factory a few years ago as it was in the same room as the 345i.
