what are they inspecting??????
Local to you? I can recommend a dealer/tech via PM in sacto.
There is no such thing as 'a standard BMW PPI;.. lots to be missed.
Price is high for a 2001 but miles are very low. DO keep in mind that "BMW maintenance" is pretty minimal.
You want to see brake flushes, coolant flushes, tranny and rear diff fluid changes. Like all you will see is oil changes and maybe on brake flush when under warranty. If it really does have 'full maintenance', it will be a rare bird (and maybe worht some premium)
Keep it as simple as possible...but no simpler.
