Before the Sunset: 2006 BMW Z4 M Roadster

A conversation in the not too distant future: "Hey, remember when inline-6 powered BMW M-cars were really cheap?" "Yeah, I should have filled a barn with them back in the late 20-teens..." "And when that first one sold on BaT for more than $100k, I thought...whoa, this must be an anomaly or a bubble" "I know <sips some soylent green through a straw> shoulda gotten one while they were cheap and before the pod people started collecting them" "Damn...pod people ruin everything".  Find this 2006 BMW Z4 M Roadster offered for $13,500 in Phoenix, AZ via craigslist.

Beautiful car inside and out.

Z4 is a fairly common car; Z4 M is not. Only ~5200 M Roadsters made for the entire world between 2006-08, and only ~2100 came to North America. M running gear from the E46 M3 (suspension, engine, hydraulic steering). M cars drive very differently from the non-M's: much more power, much tighter, more feedback through the suspension and steering. Fun!

I've never tracked or auto-crossed the car; it's been my daily driver, so I've tried to keep it as close to stock as possible.

Engine and transmission in great shape; oil analysis through Blackstone Labs shows clean bill of health every time. Oil change intervals according to BMW are 15k miles, but I always change it around 7k.

Body panels and paint in great shape. Clear bra covers front bumper, front part of hood, front part of fenders, and side mirrors.

Interior in great shape - leather/ plastic/ metal trim all look pristine.

OEM shocks replaced with Bilstein "street" shocks last year. The Bilsteins give a better ride than OEM shocks but maintain ride height (since speed bumps exist).

A couple of years ago I had the wheels chemically stripped and powder coated (the stock silver color) to correct accumulated rock chips; the powder coat has held up extremely well since then.

I've made 3 modifications:
(1) LED strip along upper trunk frame; the normal corner-mounted incandescent light is dim and poorly positioned to see anything in the trunk at night.
(2) front strut tower brace by Strong Strut (owned and operated by Paul Ebeyer, the president of the Arizona BMW Z club).
(3) DICE module for stereo - can plug in iPod for music. I will offer my iPod Touch 64GB along with the car.

I've had this car for 6+ years and debated just keeping it, but I have other fun cars on my bucket list, so... it's time.
I hope whoever gets it cares for it and enjoys it like I have.

See a better way to drive a bucket list car before it gets on everyone's bucket?

    I've found that people who actually pay for multiple Blackstone analyses prove to be great people to buy cars from. They're soooo anal're not going to worry about 10 year old brake fluid or french fries under the seats. They're also the same people who actually condition the door weather seals every 6 months with Gummi-phlege.

  2. Same logic which led me to buy my Z3 M Roadster.
    Excuse me while I go spread some Gummi-phlege.
