I took my 1990 300SEL to a new shop that is supposed to be good and asked them to change the fuel filter because the car sat a long time before I bought it. Was having No problems and getting good mileage, just wanted to keep it nice. And I thought it would be like the gas filters on American cars, not that big of a deal.

They called and said I needed a new metal line because "it's an old car and sometimes when you change the fuel filter, the line breaks". About $195 parts and labor because they broke the line.

Then they called me back to say there is a leak and I need a new rubber hose too.

I used to work on older cars than this one, and I know that occasionally you break something because the parts are old, but a gas line on a 1990? Does this sound possible and reasonable, just unlucky, or am I getting seriously ripped off? I haven't picked up the car or paid yet, so I still have a chance to argue about the bill if you experts on this forum tell me it is justified to do so.

Thank you for any help, which I need quickly because I am supposed to pick it up later today.
