if you are including brackets and paying for install $2500 is probably right...

 

There is a pair of new Sparco Evo 2 seats in black for $1458 w/ free shipping on the bay right now.....seat brackets can probably be had for $100-$200.....add two top of the line harnesses for another $500 +/-

If the correct components are purchased, installation could be done at home by most guys with a standard set of tools.....the only thing that would need to be done is the dealer would have to disable the airbags in the seats so you would not have an airbag light. So let's break it down:

Seats $1450
Seat brackets: $300
pair 5-6 pt. harnesses $500
Harness truss: $650

Total: $2900
clear airbag code: $100

Grand Total: around $3K if you install yourself......maybe around $3500 - $3600 for parts and pro installation......considering we are driving $80K-$130K cars, a few thousand is a small price to pay for some added safety and security especially during drivers ed. and auto-x days!

just my .02 cents

now, who's buying!?.....the nice thing is that, you don't HAVE to do all of this at one time!!
