Buying a non-running car is a big risk because you (or a shop) can't check the cooling system, a/c system, heater, power steering, check engine lights, suspension, transmission, and a million other things.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi everyone!
I got bitten by the Porsche bug some months back after driving my first sports car, and I think it's time to get something with more driver involvement and less lazy than my AMG Mercedes. So, I've been looking at Boxsters on local classifieds to work on and have fun with over the summer.
I found what looks like a good deal on a modded, but non-running 2001 Boxster S, and if you guys could give some feedback, that would be great.
Details:
-Seal Grey on black interior, interior in good shape, headlights have no fade
-140k miles
-6-speed manual
-19" iforged wheels
-Bilstein shocks and Techart springs
-VR Tune ECU flash
-Fabspeed race headers with cat bypass
-Fabspeed secondary cat bypass pipes
Problems:
-The car starts and runs, but the seller says it emits fumes of blue-white smoke. He said it happened about two minutes after he left his driveway some months ago and he has parked it in his garage ever since. Seller said that his Porsche technician said it is most likely the AOS
-Seller says the brakes "barely work" because "the AOS creates a vacuum leak in the braking system." I'm not sure how valid this is.
-Softtop rear window is completely faded and cracked. It needs replacement, or the top needs replacement.
He posted it for $5k, but says he won't go lower than $4.5k. What do you guys think?
I hope I'm posting this in the right section. This is my first post.
Hi BYprodriver!
Do I just inspect the rest of the engine, like belts and rubber conditions and such? Or did the failing AOS already answer that question
You mention the car is not running but listed 3 issues which none should affect the vehicle from running at least. You mention it starts and runs as well so I'm confused. The price is very attractive for a S but with that kind of mileage comes maintenance and it will add up once you find out the real reasons why it isn't running. I would get a PPI to mentally prepare yourself how much more it will cost you to get this car moving.
OK, so you are looking at an S, and that is where you should start. IMHO, This car is only a good deal if you can work on it yourself. Smoke is a sign of AOS failure, but also burning coolant (cracked head).
100 bucks and an hour fixes the AOS, but at 140K, there are a number of things that are due (or overdue).
Suspension, mounts, water pump, thermostat, clutch w/ flywheel, IMS (lots of debate on this), plugs, tubes, coils, alternator, starter are all things that cold fail. The only way it turns out for you is if you are fixing it, having a shop buy parts and then the labor will turn you upside down.
Have a PPI performed on the car, and wrench away.
Thanks everyone for all the responses! I knew this forum was a great place.
@1PorscheBoxster986, I misspoke. The seller says it runs and drives, but shouldn't be on the road because of the brakes.
@tonythetiger, Would a PPI be able to reveal if there is a cracked head? I read that this is a problem with M96 engines up until 2001.
First, if the problem was ONLY the AOS, the owner would have spent the $400 and had it repaired. There is a reason why he's selling it "as-is" and whatever the reason is, its not good.
Buying a non-running car is a big risk because you (or a shop) can't check the cooling system, a/c system, heater, power steering, check engine lights, suspension, transmission, and a million other things.
I bought my current Boxster with a failed engine and the seller swore that the engine was the ONLY problem. It cost me $1800 to repair the other things that were wrong with the car that the failed engine hid.
Buyer beware.
+1 to Tom's post regarding other unknowns.
It could be an easy fix, or it could be a very expensive car to make right. Personally, I'd price it as a parts car. If it looks nice and well cared for, a PPI could be worthwhile. The depth of a PPI depends on the shop. Call your shop and ask what they can do.
This sounds pretty reasonable. And it's probably not worth it to turn on the car when oil is being fed into the engine either, I guess?
I'm looking at other Boxsters as well, I guess I'll see how it is next weekend and tell you guys what I notice about it.

Reading many posts like this, higher mileage, 2000-2002 'S', just need some love and It could be??? - $4500 - $5500 - This car sounds like a great deal
I'm starting to think the "a great deal" is paying the $9000 - $10000 on a good running from loving owner that tried to stay on top of the know stuff.
By the time your done getting the $4500 great deal up to where it's dependable and presents nicely, now your in the $9000 - $10000.
But on the other hand if your a serious DIYer and you enjoy that kind of thing then that kinda car might be just right
So are you a serious DIYer or have a thick wallet???
