Pre-purchase walkaround
1990 BMW 535i (E34)
117,000 miles · asking $5,000
Five-year cost to own, maintenance and fuel
~$20,600
A well-built, over-engineered executive sedan from BMW's golden era, robust mechanically but expensive to keep sorted due to age and parts. Money goes to cooling system, aging rubber and seals, and the numerous plastic bits that get brittle after three decades.

What to look for on this one
Every used example of this chassis has the same questions. The bands show when each tends to surface; the gold line is this car at 117,000 miles.
Cooling system failure$550-$1,600 if not done
0typical window 80k-150k · this car: 117k, inside the window150k mi
E34 cooling components (radiator end tanks, plastic expansion tank, water pump impeller, thermostat housing) are known to age and crack, and the M30 does not tolerate overheating. Overheating, coolant loss, temp gauge climbing in traffic.
Plastic radiator and expansion tank cracking$550-$1,600 if not done
0typical window 70k-140k · this car: 117k, inside the window150k mi
The plastic tanks and caps become brittle with heat cycling and age, a classic E34 leak point. Coolant seeping from radiator seams or expansion tank, sweet smell.
Rust in floors, jacking points and rear subframe areapriced only if found
Condition-driven, not mileage-driven, so it is not in the totals and inspection is the only answer. Bubbling paint, flaking metal at rockers and jack pads, rot under carpet.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Pressure test the cooling system and inspect radiator tanks, expansion tank and hoses for cracks and staining.
02Check the water pump for weep and play, and note whether the plastic impeller pump has been upgraded to metal.
03Inspect the valve cover and oil filter housing for oil weeping onto the exhaust manifold.
04Grab the front wheels at 6 and 12 o'clock to feel for worn thrust arm and control arm bushings.
