RepairPal Certified shops can diagnose and repair your 1999 INFINITI I30. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Check with a local Infiniti dealership or salvage yard with parts interchange information to be sure. But I'm seeing different body characteristics between the 1996 and 1997 model year which makes it seem that a 1999 would not be compatible.
