Any suggestions would be wonderful.

I have an '87 300E and anyone who has a later model like mine knows what their pathetic excuse for cup holders (if that's even what they are) are. Does anyone have any suggestions for what to do? I picked up a cupholder thing from Wal-mart that goes in between the passenger seat, but since my window buttons are in the middle, it makes it hard for the passenger to get to theirs.

Also, probably a more complicated problem to solve, but- sometimes my car just doesn't want to... go. I think this may be a fuel pump issue, but i'm hoping not since they run about 250 each and there's two of them. but, i'll press the gas and no rev or anything, but the car is still running. sometimes it will slowly start accelerating, and others it will kind of shoot off. sometimes it only lasts asecond or two, and other's i'll be stuck at a green light in front of honking horns for a good 20 to 30. help?
