I ´d say Italy is really going to please your wife very soon .. rest assured.
unfortunatelly she might find herself an Italien gigolo as you will not leave the factory very often ,in case they retain Buemi and Alg...
I´m not in F1 but work for an Italien company ..
I don´t think the big teams can retain permanent staff of your level as they need to reduce next year.
On the other hand STR,lotus need to hire and I guess now is the time to look for a new place to work .
AND with Macs already part of your resume I don´t think adding half a year at reduced income will do any good to your prospects..(why did the guy stay at lower rate and worse conditions,was he worth the money at all??).
But going away to get better salary ,better position is showing that you want to go forward in life , doesn´t it? Going to italy only shows you are flexible, also good
for future ...
btw ..as a trackside repair guy I don´t think the work is really that fun ...and your wife will again have to look elsewhere.. maybe..
