How much attorney's fees are awarded to the prevailing party in a personal injury action?

We are deferential to the trial court's decision regarding the appropriate amount of attorney fees to be awarded to the prevailing party. "The reasonableness of an order for attorney's fees is a matter which lies within the sound discretion of the trial court and absent a clear showing of abuse, the trial court's determination will not be disturbed. [Citation.]" (In re Marriage of Millet (1974) 41 Cal.App.3d 729, 731.) The experienced trial judge is the best judge of the value of professional services rendered, and its judgment "'will not be disturbed unless the appellate court is convinced that it is clearly wrong.' [Citations.]" (Serrano v. Priest (1977) 20 Cal.3d 25, 49.)
