Here are two that caught my eye recently. Mostly because they're nearly identical, except that one is a C2, the other a C4 (AWD). How identical? Well, their VIN numbers are 390 apart. Temporally, they were separated at the factory by a couple of days--at most--it is possible they were even built on the same day. Seven years later, and a half a world away from Stuttgart, they're now both once again for sale, separated by a hundred miles or so. One is in Walnut Creek and offered by a Porsche authorized dealer and the other is in Sand City (Monterey) offered on Craigslist by a broker/dealer specializing in Porsches.
They're both 996 Cabriolets, from early in the 2003 model run, which means build dates in the summer of 2002. The both have under 40k miles, and they're both the same color, Porsche's wonderful Seal Grey. They each carry the initial VIN # of WP0CA29943S650, differing only in the last three digits.
The option codes above are a combination of what was described at the Stead Porsche site for #302, applied by best-guess to #692, and cross-checked against the RennTech Option Lookup page for 996 (login required). The carbon fiber trim is slightly different; note that #302 has CF around the side A/C vents, while #692 has a CF e-brake handle. There are differences in the shifter, too, that are difficult to see in the pictures. It appears that #302's is leather, wheras #692's is CF. The C2 also has the aluminum console.
There's a $10k difference in price as listed on both sites. However, a salesman at Michael Stead Porsche has offered #302 on eBay for $6k less(!!), bringing the difference in the asking price between the two to about $5k. This is largely owing to #302 having the C4 transmission, and to it being offered by a Porsche dealer with assumed higher overheads. Given the longer option list on #692, its slightly lower mileage and the 18" wheels, I'd think there's more wiggle room to be had on #302 than on #692. Or, #692 at $35k asking, could be seen as a deal.
Such a deal. Choices, choices. 4WD w/PASM or the purity of 2WD for five large less, if the CARFAX checks out on these ladies, either one would look great from outside or from behind the wheel.
