I have had to replace the battery 2 times in 9 years I've had this car.
I attribute this to the difficult climates of the Las Vegas summer (116 daytime highs) and the Reno Winters it has had to endure (7 degree mornings).
Two water pumps, and two fuel pressure regulators (one of which was due to a defective replacement part).
Other than that, it's spoiled me as it doesn't leak anything, runs smooth, and has me expecting it to start reliably.
I also put a set of Michelins on it at 30000 miles.
First car I bought with my wife the year our baby daughter was born (new).
Hope I can keep it going like my wife's 73 Cougar.
Too bad Chevy didn't keep this one in production as it was a winner.
Exterior design is wonderful.
Cooling system, interior could be made more luxurious.
