Yearly repairs? Thinking of selling

[Crono0001]

This car is just so hard on the wallet... Which I expected when I purchased it, but it never seems to drive the way I want it to. I always am fearful behind the wheel that something is going to break at any time spontaneously.

Since owning the 75k mile car in January, I've replaced:
Tires (understandable) ~ $1,000
Clutch (kind of understandable) - $2300
Shifter cables and brackets - ~$900
Vacuum leak for check engine light to pass emissions ~$2000

brakes are on the way to needing replacement (brake wear light is on)
the engine 'rattles' when I drive it
the AC Compressor is gone, meaning I have no AC (which may be cause of rattle)

Not having AC is death when you drive a black leather car in the 120F deserts of Arizona.

My friends and family just tell me to sell the thing because it is getting really expensive really fast. And there's always the IMS boogeyman around the corner too.
But I love this car so much.

So my question: How much do people spend on yearly repairs?
