Yes, watch out for those 'creampuffs' that are anything but. I encountered cars like this also when I was shopping. Patience is the key, I searched for about three months before I found the one.

 

I must've just totally lucked out. I only looked at 2. One 05 had 130k on it..it was hit in the front but of course they said it wasnt, yet the horns were both busted. Purple tint, a ragged out interior, rims missing center caps...but the crazy thing was when you shut the doors it felt like a brand new car. $6400, I walked. Next one was a 2004 listed at 7200 reduced to 6800. No pics online or bmw dealer site it was at. It didnt list a color even. I show up and it's a 1 owner car with around 166k. Black on black, no indication of timing belt, needed tires.i negotiated over the phone the next day. ,5k take it or leave it. .SOLD! $700 later for tires (know a guy) and doing the tb/water pump myself I was rolling in a reliable car.

I've learned mileage isn't everything. I bought a car with 35k more miles because I could tell it took a better path to 166k than the one with 130k.
