i can remember buying my cobra and thinking how awesome it was compared to my '87 fox body---build quality, interior, and ride quality, driveability.
then i bought my z-06 and driving the cobra felt like operating a tractor.
then i got the cts-v, and realized just how good a car can handle, perform, and have all the amenities. each step in the 3 rung ladder i've laid out for you is an order of magnitude improvement.
i suggest you hop in a luxury $60-80k car and see what it feels like. sure, your car will be faster, and all for the little money you have invested---congratulations.
a $1000/month car payment means different things to different people. carry on.
