Not a V6, straight 6, just so you know.
New seats around $250 apiece, some more some less. Depending on how big the rip, seat covers might take care of it around $150 for a pair.
New soft top with hardware $500 to $700, a frameless top just under $400.
These are general figures. You can find more expensive versions, you might find used much cheaper.
16 year old vehicle, use some spray paint.
Also change all the fluids, new belt, wipers.
Figure spending another $1000, for parts.
