I've bought a Fiesta a few months ago, and noticed that the engine noise in the cabin is kind of annoying, it's a bit too loud. It's sounding kind of like a old diesel engine, especially when accelerating or on the motorway. I don't know if it's because I'm used to my other car (it's a new Taurus V6), or if it's really some problem in the engine. Besides that, everything is fine and it's a really good city car. If you guys have any thoughts about that, I'd appreciate it a lot. Thanks.
