I replaced the muffler at about 68500 miles.
I replaced the speed sensor at about 68900 miles.
I bought this car because my husband is now a paraplegic and I thought it would be easier for him to maneuver in and out of a four-door sedan rather than our 2-door, 2-seater. Although my very first car was a Honda Civic CVCC (1975!), I hadn't driven anything, but Nissans (1 Sentra, 4 300ZX's) since. The person I bought the car from took excellent care of it and hardly put any miles on it at all. For the money, I think I got a great car. The parts are plentiful here where I live and the car isn't difficult to work on. I think I'll enjoy it immensely.
The first thing I did after I bought it was put a new Pioneer sound system in it. The previous owner had replaced the factory sound system for some reason. But I wanted something a bit nicer as I'm more of an audiophile than she is.
The body and interior are flawless and practically new. It's easy to maintain.
I feel more confident in this car than in my sports car because I can now, finally, see over the hood. There isn't as big a blind spot on the sides as there was with my 300ZX. I can change lanes and maneuver in traffic a lot easier than I had been. The power isn't there, but then this isn't a sports car. I'd happily trade power for comfort and ease of maintenance. I never thought I'd say this, but I don't even miss my Z-Car!
Every z-car owner who just read this is falling to the ground having a heart attack :-)
Please indicate which year 300zx you previously owned, so as not to miss lead readers. Thanks.
