Easy question....
It's going to depend on what prices you pay for seats, panels, etc. Some times there are good deals floating around, sometimes not. Typically (good) seats are at least $500..another $150ish for carpet, $200 for new door panels, $100 console, ~$200 for other pieces of trim. That pretty much just leaves the dash itself.
i spent 150 on carpet, about 500 shipped for all the panels and back seats and trans am door panels and all those pieces, the only thing i need now are front seats... yea and right around 500 for camaro and seems to be 750 for trans am seats
all i have to say is if you are going to do a swap, run ur amp power lines and rca's under the carpet, makes everything a lot cleaner!!! also new carpet gives you the new car smell again.. granted you can get a carpet on here for 100 bucks, but you get that new car smell for 50 bucks more
