List of timeline-undetermined projects:
-Paint - I want to go with the original Arktisblau, which I'm becoming more of a fan of vs. the Royalblau I fell in love w/ on my '87 535is parts car, and would require less PITA prep to be done right.
The Original Version:
I guess it's time to get to documenting my '86 build, and how I got here in the first place. I'm open to any comments/responses/suggestions/constructive criticism, and the like
My E28 hunt started a few years ago, when I started looking at ratty examples for my next project. I was young, dumb, and nearing the end of my '80 GMC Sierra 5.3 swap. My best friend of 15 years has spent most of that time yakking my ear off about BMWs, and growing up one my idol cars has always been the E28 M5. So, not seeing myself affording a good, driving example, I aimed a little lower at the 535is sort.
I found an '87 535is for cheap in September '13. Royalblau over Pearl Beige. "But wait, this build is about an '86 right?" Well, I'll get to that in a sec. The 535is was low mileage (118k), and had been sitting for a while. The PO said a year, but based on the amount of filth inside and out, and the expired registration sticker from 2009, I think it was more like 5 or 6 years. But I figured what the heck, bought the '87 anyway (well, more like pulled it out of the ground...first clue as to where this is going), got the engine running w/ new plugs, oil/filter, fuel filter and fresh gas and a battery - and sat on the build over the winter, as the GMC occupied my 1-car garage for a rear-end rebuild. Meanwhile, I amassed some parts for a 5-speed swap.
After I brought it home, and gave the exterior a good cleaning:


Fast forward to March. The '87 started right up after sitting since October, and I drove it into the garage.

I started tearing into it. Found these rust holes, which in addition to the rust I already knew about (trunk, fenders) and general shadiness of the chassis/suspension (which I was blindly willing to fix up), led me to give up on this particular chassis, and part out the car, keeping the motor and 'is' goodies for a future swap.



This came out w/ the bumper shock...

After the part-out started, the I punched through the rust on the driver-side rocker seam (on the inside, no pics) and revealed the driver's floor had separated from the rocker panels, further dooming the car (guess I made the right choice, eh?)
Anyway, in my subsequent search for a good shell, I missed out on a nice 130k-mile '87 528e 5-speed that I found through a friend. An 'e' would certainly help out in my daily 100-mile commute, and while it would have been a lot of work to put the M30 in there (not to mention, negate the reason I bought the 535 in the first place) it did open the possibility of an M50/M52 swap in the future, as my friend is planning an LSx swap on his E39 528i. As a matter of fact, here she was, posing with the E39 in question:



Alas, the e didn't pan out, probably because it was not meant to be. But it did renew my faith (and search) for a decent E28 shell, perhaps needing some mechanical work, as I'm more versed in that than body work.
Fast forward to late April, I came across this '86 535i on Craigslist. Arktisblau over Pearl Beige. It was cheap, so I figured if the body was maybe salvageable enough then I could swap what I needed to, and make 1 car out of the 2. Well, it turns out that this particular 535i has had all the rust repair done already, the right way. Cha-ching. The interior, while not mint (cracked dash), was extremely clean for its age/mileage and smelled wonderfully of old leather (the '87 parts car smelled like doo-doo before I cleaned it). The PO had already updated the 200k-mile motor with fresh cooling hoses, coolant temp sensors, valve adjustment. New axles recently. Rebuilt tranny. Skid plate to protect the lows against New England roads. New tires. All electrics work. Pearl Beige interior matches my 'is' sport seats. Car had fresh door and trunk seals. In short, a lot of the PITA niggles that come with an old car were mostly taken care of.
The downsides were that the steering has a clunk in it (could be cracked steering box mount or tie rod), it's automatic (I already have the 5-speed parts), and the paint needs help. In addition, the idle had a surge when warm, and the brake bomb needed replacement. There were a lot of positives about this car so I bought it, and drove it 40 miles home.



After brake bomb replacement:

PO included 2 studded snows on 3rd-gen Camaro wheels. Been thinking about either finding another 2 to round out the set, or putting them on to use the E28 for light winter duty (around town only). Don't know yet..

So far, I've been really enjoying commuting in the car, mostly because it rides like an old German car should and it rides a hell of a lot better than my '94 Miata autocrosser. It has returned 23-24 mpg on my mostly-highway commute, not too bad I think.
