2000 BMW Dinan M Roadster (Supercharged)

Disclaimer: this car is scheduled to go on BringATrailer in February. Working with one of the top BaT sellers, this car is expected to sell for around $23k. However if you have serious interest in this vehicle, I’m happy to discuss it privately before it is listed there.

$18,000 firm (lowballers may be charged a “Lowballer Fee”)

Time to sell my beloved Dinan M Roadster. I’m the third owner, bought in 2016 with 102k miles, and driven 4800 miles for about two years, then mostly stored on a lift. It is time for this special car to go on to a new home while there is still plenty of life left in this toy!

There have been three Dinan M cars in my garage, so I know them well. Two M Coupes and this M Roadster. Two of them have been supercharged. This one has many of the desirable bits, and the appropriate modifications for an S52.

The car has been meticulously maintained and I have all records from the prior owner. I’ve had it serviced by DynaSport here in Portland, and Ryan knows this car very well!

Note: Stock Roadstars with Pirelli P Zero Nero are currently on the car. Some of these older photos show Dinan Fiskes, which have already been sold.

Here is what the Previous Owner said about his history of modifications to the car:
“I originally had the car supercharged with a standard Dinan kit in 2006 by Avus Autosport in Glendale. Over time, I began to obsess over having more power--it's human nature, what can you do. The Dinan kit is a nice setup, but there wasn’t much room for upgrades, so I began to switch over to an RMS setup (main reason was to be able to fit an aftercooler in the engine to safely up the boost.) The car has a Nick G tune (Technique Tuning, Inc. ) which is tried and true and actually very conservative for where the car is currently at. I say this because a couple years ago I had RMS do a headgasket job and at the same time install new pistons and lower the compression. The s/c pulley was swapped out to compensate for the lower compression. I stopped counting the receipts around $30k so someone’s definitely going to get a deal!”
