928 (S4,GT,GTS) Buyer Tips
This is a sorted compilation of things to do or check when buying a 928. It does not pretend to be complete, but will prevent you from making obvious mistakes of which a 928 owner would say..... You should have asked...... Now you've done it......
Otherwise the 928 will turn out to become a money-pit...
or "...you race towards an early grave..." (pink floyd)
|Which type of 928 do I best buy? What
about mileage? What's important?
Here's Porsche official 111 Points checklist: 111 Point Check.pdf
You are absolutely right that 135K is higher than 40K and on car less then 5 years old it is one of the first things I consider. As cars age it becomes much less important. My 78 has 43K and when I got it out of storage after 15 years it would not run. It looked great. The problems came from rot. Almost every rubber component on the car needed replacing - all the hoses, the timing belt (which was new when the car went into storage) most rubber gaskets and even the hood insulation. It took a long time to make the car reliable.
I will admit there is a difference in how well the 928 manages mileage based on the year model. The early cars especially from 1980 on do not take well to high mileage. With the S4 Porsche made a concerted effort to improve quality. All things being equal I would rather have a "high" mileage S4 than a "low" mileage earlier car. At least after you get done replacing all the things that need replacing you will have a better car. Probably the most important improvement with the S4 is in the wiring!
A well maintained 928 can easily go 300K miles without major expense. If you are buying a car with 100K on it and driving about 10K a year then you can expect to get 20 years out of the car. By then most of us will either bored with the experience or have our license suspended. Would the premium you paid for such low miles be worth the difference in price? Sure if you just park the car in the garage for the next 20 years and look at it then it will still be a low mileage car - one that will not run but still a low mileage car. But if you drive it the difference between 240K and 300K in value is not going to buy you a McDonalds.
What you do when you pay a premium for a low mileage car over one of equal condition with higher mileage is simply depreciate the additional cost at a more rapid rate. For years I have purchased "high mileage" Mercedes and driven them until the wheels fall off. It is the cheapest form of transportation you can get and you are driving a Mercedes!. The 928 may not be the cheapest form of transportation you can buy, but I would rather put the difference in purchase price into making the car top notch than pay for depreciating value.

|For New 928 Owners (compiled by Jim Morehouse)
Many new owners are unaware of the number of sites and boards that are available on line to help you evaluate and work on your shark, so I thought I’d put together this list as a starting point. It is certainly not complete, and over time some of the links may no longer be valid. If you run into this, please let me know at firstname.lastname@example.org.

III. Parts Vendors:
"The Big 3"
In addition these sites have tips and technical info pages.
These are the only vendors I’m aware of who focus exclusively on the 928 and because of that, they are also very knowledgeable on technical issues. My personal belief is that we should make these vendors our ‘first stop’ when buying parts….let’s support the vendors who are supporting us.

Other Parts Sources:
Rennlist Classifieds: Go to www.rennlist.com and follow the links. In addition to vendors, there are people parting out cars and selling spares
Ebay: Lots of parts/wheels/cars come up. Hit or miss if you need a part quickly but worth watching if you have the time. Search on porsche (928,928*) to see the listings
IV. Bulletin Boards:
http://members3.boardhost.com/928s4vr/index.html?986420541 as well as to the new board at
Another board http://clubs.yahoo.com/clubs/porsche928ownersclub
And another http://forums.roadfly.com/porsche/928/
(I haven’t visited these last two so can’t comment on content or volume)
V. Email Lists:
Rennlist Mail List: Here you get a bunch of emails every day that covers a wide range of questions/responses/comments. If you’d like, you can elect to get a single file daily (digest mode). There is sometimes a lot of off topic or non-928 discussion but the technical content is excellent. In addition, there is a searchable archive that allows you look up previous posts on the topic of interest.
Go to www.rennlist.org/main/areas/member/index.htm and signup. This page gives the specifics of what you get for a paid membership versus a free one. Annual memberships are $17.95 (as of 12/01) or $32.00 for two years. Although you can access many features for free, this is such a valuable resource that I hope you will support it by joining. The people on this list have helped me a lot.
For both the mail list and the bulletin boards, you’ll be pleasantly surprised by how knowledgeable and helpful these folks are. Note that when you post a question, it’s important to include the year of your car, transmission type, and mileage as well as a complete description of the problem. You might want to check the archives as well before posting.

VI. WEB SITES
These contain some of the best info out there since they’re put up by people who have BTDT (been there, done that) rather than ‘trained Porsche mechanics’. This is just a sampling and I know I’ll leave out some important ones but it will get you started
Greg Nichols Tips Site: a MUST read. A collection of questions and answers on various subsystems and procedures http://www.nichols.nu/tips.htm or http://ourworld.compuserve/homepages/nichols/tips.htm . Greg is also including links to web pages that people have put up on various procedures and these BTDT (been there, done that) explanations are a tremendous help.
928 Owners Club: www.928oc.org Right now most of the content is free but at some point it will be limited to members. Membership fee is nominal, again I think it’s worth supporting. The web site was pretty static for awhile as people got busy with the jobs/family/etc., but there is renewed interest in maintaining the site.
Porsche Club of America (PCA): http://www.pca.org
Recall Data: http://www.alldata.com/TSB/
Bosche: (the maker of the fuel injection systems and much of the electronics used in the 928)
This site has a lot of links to other 928 related sites: http://www.eatel.net/~dslabat/928links.htm
Here are some Maintenance Sites. The sites may be duplicated under "More" but since these were given to me as relating to Maintenance I thought I’d include them below. This list is certainly not complete and you’ll find sections on various maintenance procedures as you browse through the sites listed under "More".
