Replaced noisy fuel pump under warranty, replaced passenger side power window motor myself, replaced 1 rattling exhaust clamp.
Otherwise no repairs, only maintenance. I change the oil myself.
This has been a simply wonderful car: completely reliable, fast, agile, and affordable. It has held up well in the 6 1/2 years since I bought it new. It doesn't use oil, has no fluid leaks, and fewer rattles than I expected for such a stiff suspension.
The t-tops have never leaked or rattled.
On my last long 70 mph highway trip my mileage was 28.66 mpg, which slightly exceeds the EPA of 28.
The car gets lots of compliments; I do not ever think of selling it.
I love the feeling when driving around in a Z28. Nothing beats that feeling.
