Well I just wrote a diatribe of things to watch for and be aware of, but before I could finish my computer overheated crashed and I lost the text. I will try to be more brief this time.
Alright thanks guys, I'm considering one that's a 94 with 250,000 miles, bunch of new parts, for only $1,350, craigslist. Car looks as if the owner was meticulous about the maintenance.
Depending on how well the car has been maintained this
could be a great buy. The parts on these cars alone are easily worth a couple thousand bucks.
Major Things to Look For on Aeros with HIGH mileage:
-RUST
-smoke from the exhaust
-cooling system issues
-turbo problems
-TCS/ETS throttle issues
RUST:
FENDERS:
The fenders on the 9k rust out really easily right at the wheel arch where a half circle cover plate attaches and secures the plastic weather gaurds.
Replacing the fender is a pretty easy process but finding one in the right color can be hard.
The strut mount bolt area under the hood is prone to rusting and is essential for the cars drivability.
STRUT MOUNTS:
The rear strut mount area is where the rear suspension attatches to the frame of the car on both sides of the gas tank. This area is often neglected and can easily put your car out of comission if not tended to. Look for rust where the suspension meets the frame, if you see A LOT of rust this is bad.
Luckily the car has a really good weather sealant on the bottom of the car so you should see literally no rust on undercarriage.
WINDSHIELD PILLARS:
The pillars/poles/bars on either side of the windshield at 200,000+ will almost certainly be starting to see some surface rust. The pillars are strong enough that this is more of a cosmetic issue than a structural issue.
You can use chemicals like POR-15 to stop the rust at its source after you have cleaned up the affected area.
SMOKE FROM THE EXHAUST:
This could indicate a broken head gasket, bad turbo, etc. It could also however be a number of benign issues which can be solved rather easily compared to a head gasket. At over 200,000 miles in an Aero, a head gasket repair in the future is very likely. I've heard BAR's leak sealer can work well if you catch it early.
COOLING SYSTEM ISSUES:
As discussed earlier this can be expected, watch out for the heater core hose and all the other radiator hoses and senders/thermostat/switches/relays/fan operation.
TURBO ISSUES:
If the oil hasn't been changed regularly with good oil the turbo will start wearing out. The waste-gate actuator can get quite rusty and may need to be adjusted at some point or replaced. At high high mileage there's always a possibility of some leaky or cracked intercooler hoses and/or intercooler.
TCS/ETS THROTTLE ISSUES:
Very common problems at high mileage that can potentially cost a lot $800 for TB, $200+ for other electromechanical parts, $100+ for valves and solenoids. This is why people many people say the non TCS/ETS Aeros are the better way to go. You can always convert a TCS/ETS to a non TCS/ETS throttle system but this is a pretty big job.
