[urq] 83 on ebay

[formarty at comcast.net]

There is an 83 ur-quattro back on ebay. This is the third time its been listed The owner says he paid 16K a year ago.
Had a buy it now for 16K . I was high bidder at 6100 but well below the reserve. The buy it now is $ 13,500.
Talking to the owner, he stated the only issue the car has is that after a ride that gets the engine to normal temperature the car will not re-start immediately, you have to wait 10-15 minutes before it will re-start.
Can anyone tell me what they think the problem could be and what the cost to repair might be? My A-4 lease is up in 6 months and am thinking about an ur-quattro for a daily driver since my commute is less than 3 miles.

Thanks,

Marty
