Im looking for a good Diesel German Car, eyes these - BMW 320-5/330D, Merc C220CDI or Audi A4 2.0TDI, registered around 2000-2001. What area's should I look into and how are there performances generally. I tried looking over the net for Diesel German Marcs performances and came up almost empty handed, so looking to you guys for some input.
My opinion is basically, a Diesel 2-2.8 liter engine can do well on fuel and has enough torque to pull its weight and accelerate at a decent rate.
What concerns should I have - or what should I keep a look out for.
