I am planning to go to Barcelona end of May to see an old buddy of mine, I have booked tickets to Frankfurt, I found that car rentals are dirt cheap in Europe but I can’t say the same about the price of gas, my question is how what makes more sense, take a rental car and pay your own gas (rental is 100/month EU) or travel by train, TGV. Also I know that some VISA cards will cover your rental insurance – any idea which ones?
Did you check out Ryanair?
I don't know to what you are comparing but car rental might not be as cheap as you think, maybe in countries like Spain, you can get a good deal, but in Germany I doubt it. (100/month deal I have never seen) but you would need to pay for petrol, and that is expensive overhere. Besides that you would be paying for using the motorways in France and Spain.
Ryanair doesn't fly Frankfurt - Barcelona (or Girona), but Clickair, Condor and Air Berlin do, so check them for the best deal. In my opinion that's the way to go if you want to get to Barcelona fast and cheap.
If you are going to Barcelona, it would have made a lot more sense to fly to Spain or Southern France instead of Germany. (What were you thinking?) It is like flying to NYC when you really want to go to Chicago. (Unless the idea was a road trip across Europe.)
Renting a car has the big downside that you would need to find a company that allowed you to take the car from Frankfurt to Spain. Fuel alone will cost you around 120 EUR one way for the distance. Add to this the road toll in France and the whole project gets mental.
Flying is the best way. If you read a bit of German:
Or use http://www.skyscanner.net
Consider also alternative departure points like Frankfurt/Hahn (HHN) and alternative destinations to Barcelona (like Girona and Reus).
RyanAir flies from HHN to Reus for currently 0.01 EUR one-way at certain days at the end of May. This is a special webfare to which taxes are added. Your total ticket price will end up being somewhere in the neighborhood of 40-100 EUR return, depending upon the day of travel.

If you wanna fly I'd rather fly to girona than Reus by the way, it's better connected to Barcelona in my opinion
IF you want to transfer just after landing at Frankfurt Int. and you decide on a flight from Frankfurt-Hahn, then allow yourself some time to get there. The transfer itself is 1.41 by train and bus, but don't forget you need time for lugageclaim, and to arrive in time for check in for the flight at Hahn Airport. (transfer should cost you 11 euros)
