10. PURCHASING

Q. What should I look for when purchasing a used M3?
A. There are a few notable items. If purchasing a 1995 or 1996 M3, make sure the water pump has been changed to the metal impeller type (discussed in the Engine section). On all M3s, verify the following: the radiator neck is not cracked, compression of all cylinders is within spec., there are no parts with DOT-R labels (discussed above), and no fault (may be minor) or over-rev codes have been saved. Finally, if you are serious about your purchase, you should have the vehicle inspected by a certified BMW technician.

Q. What are DOT-R labels?
A. DOT-R (Department Of Transportation - Replacement) labels are used in place of the standard BMW label (includes your VIN number) indicating a particular part has been replaced, e.g., the hood or fender, and is often attributed to a motor vehicle accident. For more information visit Unofficial BMW at http://www.unofficialbmw.com/images/all_vin_chart2.gif which includes a further explanation of DOT-R labels.

Q. What is a Certified Pre-Owned (CPO) M3?
A. In short, a CPO M3 is a dealer inspected and certified M3 with an additional 2 year / 100K mile factory warranty. For a detailed description, visit the BMW NA site at http://www.bmwusa.com/.

Q. Where can I find a used M3?
A. Some helpful places to start browsing for information would include: enthusiast forums (listed in Other Information), AutoTrader.com, Cars.com (also includes local newspaper listings), and eBay. In short, be prepared with a list of questions for the sellers and be especially alert on eBay for fraudulent auctions.
