Is This Q for You?

1991 INFINITI Q45 A 4dr Sedan

A beautiful but flawed car. Anyone who goes near a used Q with the active suspension will regret it for the life of the car. Based on my experience it requires total replacement about every 4 years at a cost of $8-10K. Not exactly an acceptable maintainence item!

1991 INFINITI Q45 A 4dr Sedan

Perfect car for just about anyone. A lot of horse power to pack a punch. Fun and useful. There's plenty of room but it's not too big. Works great for a family car as well. Best Car I've ever had. Even better than my 2006 Toyota Camry. The Q45 is a great car!
