For sale super rare special racing edition A6 , 4.2l quattro . 129k on dash but actual is 98k, but motor seals need to be repaired or replaced.

Used car for 2 yrs and roomate ran it with very low antifreeze..overheated but engine might be restorable..cant fix as I hv just purchased house and need to renovate so I'm screwed. Dont want to part out car due to its condition, and rarity...pls dnt call/text with ridiculous questions..this car is not for the average person who knows nothing of cars lineage...its very rare and it was produced to go against BMW's, benz's...handling is race inspired so is all amenities...I can negotiate with serious inquiries only...thnx
