Hi guys - my parents Boxster S recently stalled at a stop sign, and when brought to a mechanic, we were told they thought it was the IMS (honestly, not sure how thoroughly they looked at it).  Anyways, my parents are 70+ and didn't want to deal with a repair. 
Car has about 110k miles and up to this point, didn't have any issues and had been serviced regularly (can be seen on carfax).  In addition, last year, we had $5,000 of suspension refreshening completed.  
Looking to sell this to someone who perhaps can throw in a new engine and let this car continue to live on.  Car does not come with the hard top (we recently sold it to a neighbor).  
Asking $3,000.  Car is located in Walnut Creek, California.
