Is 70K correct? The car looks really used on some pics.
engine problems with 70K means-no maintenance or fake odo
The electric motors (cabriolet top) are really expensive..
2 in the front / 2 in the back.
91162405603 Elektromotor front 686,87 Euro you need 2
91162411700 Elektromotor back unavailable at Porsche Germany
91162405603 $543.90 -- pelicanparts
91162411700 $141.90 pelicanparts specialorder
Normaly the front motors are broken (over 1.1K$), but if nothing happens??
No motor tries to work?? Maybe its only an electrical problem
the electric top wont open without the key in the right position!! Sometimes hard to find.
I dont know the US price range, i think 18K is to much..if the engine needs work.
Nothing is cheap..a set of 15" Fuchs..??
AC ??
5-10K$ in spare is normal..
There is no difference between 18 + 5/10 and a mid 20K car in good
condition.

Do a PPI if you like the car..and keep in mind you will end up mid 20.
