In Jan 1990, I purchased my new 1990 300ZX From Rosenthal Nissan in Tyson's Corner, Virginia. During the first ten years the Z was serviced by the dealer. Since about 2000 major service/maintenance/upgrades have been performed by Bernie Bilski. When I moved to Florida in March 2008 I brought the car with me. About 2 1/2 years ago I dropped the Z off at Bernie's for 120K maintenance/engine overhaul - Yes Bernie is that good! Car runs great!.
