Buying a used E4 just for the doors


I am thinking of buying a used 2007 E4 just for the hard doors. I bought a new 2013 a few months ago and hard doors were priced at close to $4,000.

I would like to take the doors off of the used 2007 and put them on my new 2013. Has anyone installed hard doors before. I am concerned about drilling holes and getting them in the right spot.

I would then sell the 2007 for about $1,000-1,500 less than I paid for it.
