If I use another mechanic for an engine swap I will be sure to include the labor.
Honestly, I love 16510 and according to Facebook I am married to it. I consider driving and working on it to be a pleasure. Would you let another man please your wife?
Oh and as far as disclosing issues, I already have some unexpected stuff to disclose that really sucks. Last night I discovered I have a radiator leak. If have to replace it i could possibly go over $500 for the year. Time will tell.
And log 10,000 miles?
