First off, could you do the job and if so, how long would it take you and what's your time worth?

Secondly, are you happy having your car back and how it works?

Third, is this friendship worth risking over money...meaning, five years down the road would you wish you had stayed friends verses making an issue over this?

At the end of the day, doing business with friends always comes with a risk and not having a quote leaves you open to spending more than you expect. This is why I do most everything myself and if I have to have something done, it always comes with a firm quote and a call to notify if something comes up outside the expected costs. Best of luck working this out.
