So sorry to hear about your VX :(
Is it at that Dodge/Isuzu dealer in Lawrenceville? I think it's Dick Greenfield.
Whenever I've been there they have not seemed very Isuzu savy. I've never actually decided to get work done there though (they scared me away twice).
Or is it out at Haldeman Nissan? Are they an Isuzu dealer too?
There's also a dealer in Richboro Pa, Davis Pontiac - Isuzu.
I wonder if Glen Wood could help, he has a foreign car repair shop in Morrisville five minutes from Trenton NJ and is a fellow VXer. His shop has been there for years, must have loads of experience, but I just discovered he is a member of this forum recently.
