So, I'm at a bit of a crossroads with my E82 BMW 128i. I bought it 2.5 years ago with the intention of turning it into a track car that was still nice enough to drive back and forth to the track and maybe a bit on the street. To preface this, I bought the car for dirt cheap and it was heavily abused by the previous owner(s). It was also previously in an accident and not everything that should have been replaced was replaced. Because track car, I didn't really care at the time as it made me less hesitant to abuse the car on track.
But before I could even get started with track mods, just to get the car in good running condition after I bought it I had to replace quite a few deferred maintenance items due to previous owner neglect:
Water pump, thermostat & coolant – $514 (DME code for the water pump, figured it was a good idea before I ended up on the side of the road)
Coil packs & spark plugs – $186 (Bought the car with a misfire. Because of course I did.)
Serpentine belt kit – $90 (Maybe not urgent, but on these cars, you don’t gamble with the belt that likes to feed itself into the crank pulley.)
Air filter & cabin air filter – $52
Replaced A/C Schrader valves – $270 (to get A/C working again/holding a charge)
Reman steering rack & pinion, shaft, reservoir & fluid – $1,055 (The steering rack was toast when I bought it. The car wouldn’t drive straight)
Driver-side door seal – $148 (had a massive hole in it)
Oil filter cap leak fix – $36
All fluids & plugs replaced – $195
OE “M” shift knob – $122 (The stock knob literally flew off mid-drive and refused to stay on)
Shifter bushing rebuild kit – $80 (The shifter felt like stirring a pot of soup with a pool noodle.)
Suspension refresh – (The OEM shocks were dead. I upgraded to Bilstein B12s, but to be fair, I could have saved quite a bit of money with a stock set of shocks from FCP Euro would’ve been about $380)
Brake pads & rotors – $301
OE fuel pump & filter turret – $357 (Fuel gauge didn’t work. Could’ve been accident-related, but the stutter suggested fuel delivery issues too. At the end of the day, it needed doing.)
ABS sensor - $$$
New tires (initially Continentals on the street, but I eventually swapped over the Michelins)
Just about every exterior light you can think of- $$
This is to say nothing of the long list of items I replaced as a result of the previous accident, or things the previous owner(s) somehow lost:
-Seatbelt/airbag related sensors/components
-Carpets
-Jack pucks
-License plate frames
-OBD cover
-All three underbody panels/trays
-Rear wheel (they put the wrong sized wheel on the rear)
-DMTL pump/charcoal canister
-Right rear axle & wheel bearing
-I replaced the right rear suspension entirely (knuckle, control arms, etc) to avoid anything else that might have been damaged in the accident
-Exterior window trim
-TPMS module
-Replaced missing wheel bolts
-Reman right rear brake caliper (technically, this one was actually my fault!)
I also replaced quite a few things that probably didn't need to be done, but I was trying to be proactive to avoid issues in the future; so I replaced:
-Radiator hoses
-Timing chain tensioner
-VANOS solenoids
-Motor mounts (while doing the oil pan baffle since the subfame was already down)
-Cleaned up the headlights, etc.
Even with all of that done, the headliner could use a refresh, as could the fairly rough-looking paint.
To get the car ready for track work, I did quite a few mods:
-3.73 diff with Wavetrac LSD (stock is 3.23 open diff)
-CSF Racing radiator
-OEM 135i oil cooler (much bigger job than I expected!)
-OEM DISA 3-stage intake manifold (those OEM DISA valves are pricey!) and a tune to actually activate the 3SIM
-Apex wheels & 200tw tires
-OEM M3/1M control arms (front and rear)
-Bilstein B12 cup kit (in retrospect, I should have went with something much stiffer, even though I like the B12 setup on the street)
-Dinan camber plates
-Condor speed baffled oil pan (again, much bigger project than I expected!)
-OEM Euro intake & K&N filter w/Turner Motorsports intake elbow
-Whiteline rear subframe bushing inserts
-Hawk ER-1 pads, stainless steel braided brake lines & SRF fluid
-Purchased BimmerGeeks ProTool software (plus K+DCAN cable) and coded out the OEM nannies
The car is now considerably quicker, handles better, is more enjoyable to drive and can handle track time reliably.
Here's the kicker: I'm no longer interested in tracking cars. Not just this car, but really, any car. I went to a couple of events this year and I just can't get into it anymore. Which has led me to only driving the 128i on the street. To be clear, the 128i is actually a really fun car on the street. But in the past 2.5 years of ownership, due to having a take-home work car and multiple cars in my stable, I've only driven it about 8000 miles (purchased with 133,000 miles, now at 141,000). Which, for somewhat of a "weekend sports car", that's not bad. Far more than I drove my former S2000.
The issue I'm having is that in addition to the boatload of maintenance I've done to the car in the past, here recently even more problems have crept up on me:
-The A/C went out again. This time I suspect it might be the dreaded evaporator... which, if true, it's listed as a 12+ hour job that requires a full dash removal.
-The front right wheel bearing is on it's way out.
-I just replaced the battery and coded the DME for it.
-The parking brake is pretty loose and now won't hold the car on a hill. I suspect I can likely just adjust it, but there's always a chance I might need to replace the shoes.
-I find myself missing gears from time to time, which makes me think I should likely replace the transmission mounts.
-I need to adjust the driver's window to cut down on freeway wind noise (replaced by previous owner, never adjusted correctly, or just doesn't fit right).
-As mentioned above, it's a good idea to re-do the headliner as it's pretty rough (was likely removed after the accident by the previous owner).
At this point, I'm burnt out on wrenching to say the least. The car is still a blast, especially on the right road, it's actually more fun than it's spec sheet would suggest, but the never-ending list of issues sometimes causes me to consider buying a book of matches, a can of kerosene and burning it to the ground.
I guess I'm at the crossroads of:
1. I've done so much to the car. It's really good to drive. Do I really want to throw it all away?
2. This car is an absolute money-pit and I'm starting to feel like it's never going to end. Perhaps it's better to cut my losses and move on in order to help maintain my sanity. Perhaps going back to a newer, lower-mileage car that I don't feel the need to modify isn't a bad idea.
I can admit that putting so much money into a 17-year-old entry-level German car is a very poor decision, both financially as well as from a physical therapy perspective (my lower back isn't what it used to be). But I also know how much I've put into it... but thinking about how much more I'll have to invest has left me thinking "perhaps I should save that cash and invest into a newer car that needs nothing".
I'm sure some of you have been to this exact place. Any thoughts and experiences would be greatly appreciated.
