One of the reasons why I bounght an Audi A4
 

Because the fuel door is on the passenger side.

This might sound stupid, but think about it folks.
If you've ever owned a car that had the fuel door on the driver's side, how many times have you banged your door as you were getting out on a concrete block or pole that they have at gas stations. Or you parked too close to the gas pump and you couldn't get out.
Call me whatever you will for not talking about the typical stuff like, I bought it for the Quattro or I bought it for the tune-ability. But for me the location of the fuel door was one of the decision maker.

ummmmm.... ok.... i bought it cause chicks dig it =P

Some of those old Jaguars have it on both sides, should have got that if it's your main concern???

I bought mine because I have a small....
 

...budget.

Yeah, the XJ6 from the 1970s.

It's a safety design, if you need to gas up on the highway...
 

you will be standing on the shoulder, not in traffic.

weiner?

I thought that it was so that you don't open your driver's door and hit the pump!

I think it sucks, It's more convenient to have it on the drivers side.
