Clarification Requested

Hello ronp

Are you saying the engine block sustained a crack do to the front end collision accident or do you mean the engine blocked cracked causing you to have a front end collision??

Neither of the above sounds correct.

A vehicle with a cracked block usually doesn't run well enough nor long enough {if it runs at all} to sell to an unspecting buyer for any reputable dealer to even offer for sale on the lot.

Nor is it likely you can sue anyone. Question is?...Sue whom for what?

"Lemon Laws" do not apply to used vehicles either.
