My brother tore his LCA out of the front subframe on his Mazda MX6. They told us the frame damage would cost about $2000 to fix. We got a new front subframe off someone from the internet and installed it costing us about $100. We were lucky as that part unbolts, but if your damaged part doesn't unbolt them maybe you are screwed. It doesn't make sense to pay $2000 to fix frame damaged on a 4G since their value is so low anyway.
