White, on black on black Z4 M Coupe - Clean Title
Make me a reasonable offer
Genuine M car with S54 motor with the factory updated/faster than M3 processing ECU
6 speed manual (they all came this way of course)
18x8/9 wheels with 5mm spacers up front and 10mm rear.
Totally reversible rear wing that is polarizing in taste but also genuine carbon fiber and highly functional on a short wheelbase car, accompanying rear diffuser the aero works very well and is very well balanced.
Yes its higher mileage, yes everything works, yes it's by far the cheapest fully functional, clean title M Coupe in the country.
Currently has no mufflers but does still have the resonators and cats so no issue passing emissions.

I bought this car one year ago after starting down the rabbit hole of s54 swapping an 87 e30 iS. As things typically escalate, I ended up buying this car since it was where I was trying to end up with the e30 anyway but handles significantly better than an E30 ever will. This is an entirely different league by comparison and that is how I justified it. Hoon logic. I picked it up in Rochester, NY in 2017, drove it 3,200 miles over nearly nine days taking the long way home without any issues.

The chassis is very very stiff for a road car, factory dampers and springs but man is this a truly focused M car. Most of the reviews mention this as well.

This car is surprisingly rare, it is one of only 1,500 in the states over a three year build period. That's pretty legitimately uncommon and some say the prices will soon begin reflecting that given the post 10 year run the Z3 M Coupes made, especially S54 examples.

Positives:
Truly Very Very Rare
Factory M Car
Great handling
Great sound
Going up in value, this is certainly a good time to buy one of these cars
Hydraulic steering!!
Fully defeatable driver aids
No issues to drive it across country like I did, just bring ear plugs!
Fully sorted daily driver capable, starts without fuss every time
AC blows cold
Seats are powered, heated and wonderful, one of my favorite surprises about this car over the course of the journey home was that my back never hurt in these seats. I'm looking for a set in one of my other projects.
I'm not one to put wings on road cars but this one came to me as such and it grew on me and now I kind of like it, its loud just like the exhaust so they match.
The sound this car makes above 4k rpm will make you believe in something other than god. It is all that is right about a high revving NA M car
I have changed all the fluids in the last 3 months. Proper 10w-60 in the motor of course.
New 255 fuel pump at the same time
New brake pads(Hawk Street and Track), spare street Stop-Tech ones and fresh bleed
R888 Toyo Tires all around, fronts are less than 300 miles on them
Re-coated calipers from yellow(gross) to M Sport Blue
NEW(!) ridiculously expensive(!!!) OEM(you have to, I promise) brake rotors front and rear. Basically the only other car that uses these size rotors is the E46 M3 with the competition package. You can find mislabeled options that claim to fit but they don't, I promise. It was a hassle to track the proper ones down. $550 each rotor, $2,200 a set and they are damn good looking too. Factory two-piece, aluminum hat and factory cross drilled. Totally badass brake rotors from the factory. Less than a 2,000 miles on them.

Supporting evidence of why this car really is something unexpected and surprising:

A long but very in-depth video: http://www.thedrive.com/video/8603/whats-the-best-10-year-old-sports-car-you-can-buy literally half the reason I bought this car was that video.

The Bad:
143K miles is not low. S54s seem to be able to handle that just fine and all service is up to date and the car has never had any weird engine mods/boost etc. I put a K&N air filter in it, thats it. Period.
Due for vanos eventually but NO ISSUES currently, also, for what it's worth, I was all forum freaked out about vanos issues and have since realized its a bit of an overblown issue. These cars are much more reliable than the S65/85 M motors from later generations of M cars with their rod bearing issues. Hell, I have an S14 in the garage with holes in the block but this S54 motor hits a sweet spot for BMW with reliability, commonality and performance.
The previous owner painted it an unoriginal but admittedly cool color, it has a metallic blue hue to the white base. Originally the car was black and if I kept it I would likely go back to that but priorities have changed with my car hobby.
Does show a fender bender on the carfax but nothing more than that and many thousands of miles since that. I can find no evidence of it on the car beyond the new bumper cover.

Call with questions, I'll happily talk your ear off with a fellow enthusiast so long as you are serious about buying the car.

Cheers,
Patrick
