Looking back on my records of GNX information - GNX 137 for sale ON EBAY FOR $30,000 - buy it now, PLUS there are MORE THAN 4 OWNERS...
in 2003 it had 36,000 mile and 2 years later -- add 500 miles, I dunno about cars not driven.... seals leak --
BTW what about the famous REAL MAIN SEAL, maybe with not driving them they just stop leaking.... or is that GNX's are exempt from this problem with GN's
