928's and associated parts and accessories are quite popular on Ebay. Just about about everyone on this board has bought something there. Many of us have learned from our experience. Here are some tips that you might want to think about BEFORE you bid.

Shop around for that part, many times those OEM or NOS parts can actually be had from the big 3 or other supplier for less money.

WATCH OUT for outrageous shipping and handling charges.

Be wary and leary of claims like "Same material as OEM" or "Better than OEM".

There are pirated copies of Shop Manuals of poor quality going for the same or sometimes higher prices than the originals. Also PET CD's and Shop manuals on CD. (search the archives for more info)

Check their FEEDBACK! New Sellers (those with sunglasses) may be the bad guy just changing his name. Be careful. An occasional negative feedback on a high volume seller is probably unavoidable. However if the seller has 12 feedbacks and six are negative, I wouldn't take the chance.

Private Auctions are generally for HIGH END items such as real estate and the like. It is intended to keep the bidders from being harrased from unwanted and unsolicited emails and offers. Unscrupulous sellers will set up private auctions on low end items so that no one can warn the bidder of the screwing they are about to receive.

Check the bid history on an item. There have been known cases of "SHILL BIDDERS". If something looks suspicious, proceed with caution.

If you are wanting to bid on a 928 and can't go there to check it out yourself, place a post on the board, someone may help you out that lives near the car. I have two friends that bought cars and both essentially got screwed. An MG Midget and a Mercedes 450 SL were both advertised as in "VERY GOOD CONDITION". Both ended up being towed home and actually in "LESS THAN FAIR CONDITION".

"Buy It Now" items are sometimes from a seller that "NEEDS THE CASH NOW".

When I want something, I usually take one of two approaches. Sometimes I will bid the highest amount I am willing to pay up front. If I really want an item, I am there at the end. I don't waste time and money by running up the bid. In the last moments of the auction, if the price is not higher than I am willing to pay, I bid that price. (sniping)

I am fortunate in that I have not been taken. The purpose of this post was not "Who" to watch out for, but "WHAT". Hopefully others will post some more helpful hints.

Before you bid on an item it may be wise to check this site for the seller:

Post Items For Sale & Cars/Parts Wanted + Rennlist Charter + Sponsorship


If you want to post 928-related items or cars for sale here, or request parts or cars wanted to buy, you MUST be a paid Rennlist Member.

Please include a detailed description and the asking price in all For Sale posts - every item, every time.

Any 'For Sale' and 'Parts Wanted' posts by non-members, or by Members with no asking price, "Best Offer", "Make an Offer", "Highest Offer over $xx", "Email for Details and Price", etc. will be removed without notice.

Membership Has Its Benefits

OK, so you've paid for Membership and want to sell something. Great. While not mandatory, it is recommened that you list a discount for paid Members, or an additional 'fee' for sales to non-Members. You've contributed by joining, why shouldn't they in order to partake of offers presented on Rennlist.


From time to time we encounter individuals who troll the forums looking to sell parts. Be advised that we support our paid Sponsors, and hope you will too.

Unsolicited private sales are NOT in any way endorsed or authorized by Rennlist. and as such, Rennlist may not be able to provide assistance in resolving any disputes. Even paid Members that approach you should be dealt with warily unless you are sure they have a solid reputation.

If you are ever approached with parts for sale via email or PM - by a Member or non-Member - please contact the forum Moderator for guidance before proceeding: Send a PM to the Moderator

Posting Links to eBay Auctions

If you want to post your ebay link here, post a reasonable Buy it Now (BIN) price that you will sell it for.

If you get a taker here, you must end the auction early and sell it to the Rennlister at the BIN price.

Signs of impending disappointment for a new 928 owner:

"I spent every nickel I had to buy my shark, I hope it doesn't need any repairs for a while, I'm broke"

"I've never worked on a car myself, I don't even own basic tools"

"I got a great deal. Sold my reliable daily driver because I only have one outdoor parking space at my apartment building. All I own now is the 928."

"I know nothing about mechanical stuff. I did find a mechanic who say's he's seen a 928, but never really had to work on one. He does speak with a cool foreign accent and has foreign cars sitting around his shop."

"I hear the good thing about German cars is that they're built like tanks. I mean, drive the wheels off it for a couple hundred thousand miles and maybe change the oil now and then"

"Sure, the parts are a bit expensive, when you need Porsche originals. So, I save where I can by using generic motor oil, budget coolant, heck, I just snagged a used timing belt off Ebay, in case I ever need one, but I doubt I'll change the timing belt unless it breaks or something."

"$350.00 for shop manuals? I don't think so. I'll just guess and try to apply MY extensive knowledge which I gained by fixing the family lawn mower for years."

"Come on, I only paid $6,000 for this car. I'm not dumping $2,000 in preventive maintenence parts into it...........(hot chick walks by)."hey baby, this was a $70,000.00 car not long ago!!!" (see the irony)

And the number one sign of impending disapointment for a new 928 owner is......"Rennlist, Big 3?, never heard of them!"

Default The Dark Side

Here's a site that provides guidance on conducting internet transactions, in an effort to to reduce the chance of you being scammed or cheated:

The following site provides a listing of individuals and businesses that you might want to consider avoiding in internet auctions, sales, etc:

Disclaimer: Rennlist does not verify the validity of the claims expressed in the above link, but only provides this informational resource as a 'word to the wise' for the Rennlist community. If you feel you have been wronged in an internet transaction, you might consider posting the information on the site linked above.

What To Do If An eBay Transaction Goes Bad

Courtesy of Wade T:

First, file a complaint with ebay for item sent but not as described. He will then have 10 days to respond in the dispute console.

If the seller hasn't swept their account and there is still money in it, PayPal will have "frozen" the account until the claims are paid out.

If you DID pay using a credit card, you should call your credit card company and just "ask" about the charge back procedure. If they can assure you that you're covered, cancel the PayPal dispute and go with them instead. You cannot do bot at the same time.

In the event PayPal can't get any money back for you and you didn't pay with a credit card that will cover you, start filing with the following agencies.

* eBay's Fraud Protection Program. > >
* Seller's local police department > >
* State, County & City Government Consumer Protection Offices > >
* USPS Mail Fraud Complaint Form > >
* IFCC > > (
* FTC Federal Trade Commission > >

Default Searching the 'Other' Rennlist Areas

From the Rennlist Admin - John D.:

Hi folks,

I just added another Rennlist Search feature from the Rennlist e-mail discussion lists (the main lists - 911/964/993/Carrera, 924/944/951/968, 928, Racing, etc.) including over 2,000,000 posts from 1998 - 2003. THESE MESSAGES ARE DIFFERENT then those found in the Rennlist Forums - as it's a different Rennlist Discussion venue altogether.

It also had a free text query based interface, so you can type in "questions" - and the relevant threads will appear in ranked order as compared to your question you are asking.

Here is the link:

And no - you do NOT have to be subscribed to the Rennlist e-mail lists to perform these searches.

I hope you enjoy....

John D.
