Its alot of car for the money...I don't drag race mine so I much prefer the IRS...it actually surprised me because I like solid axle stangs because of how you can slide them sideways...and the IRS is pretty progressive at the limit.
I got a one owner 99 Cobra Vert with 40k on it for $15,000....you may have to negotiate quite a bit...but you can sometimes find them. And this car is clean enough to eat off of.
