I purchased my Speedster from Nat about 6 monthes ago and heres my story. I questioned Nat on three different Speedsters and picked-out
a black one. He sent me pictures and we negotiated a fair price. The
process was painless. The car arrived when promised. When the car arrived it was as expected but the wheels (fuchs style) had wheel caps made out of cardboard, painted silver with Porsche stickers on them and glued onto the hub - pretty cheesy. The car was very sluggish for a month until I had it towed to Munk's Motors. $1,200.00
later the car is running super and wheel hubs replaced I'am content
with my purchase. Maybe you should plan on tune-ups, inspections, etc. in your budget. Oh, the stereo does not work which was not mentioned to me. But this is not a problem as I would up-date any way.
