Thanks Mercer,
I already made an appointment at the Queens dealer for Tuesday. Aside from the Staten Island one - Manfredi Isuzu, this one is the closest. I think Adam and George weren't too happy with Manfredi, so I decided to try Queens Isuzu. The address listed on the site is different from what louielou2k siad, but they transfered me to the service dept. and it's the one.
The service dept. is also only open during the week, but I can drop my VX off in the morning, then take subway to work, and pick it up at the end of the day.

If I'm not happy with Queens Isuzu, I'll try LI Robert Isuzu next.

PS in case anybody interested, they quoted me $142.95 for the 7.5k service. Sounds right?
