Shamless plug for Whitebear Mitsu in 3..
I recently test drove a TDI for fun, and was very impressed, 40+mpg, 240tq, and deisel longevity. I will definitly be looking into them when I purchase another car. not sure what is in the 15k range they seem to hold their value really well but alot have higher miles as they are bought to drive, here is a quick one I pulled of CL
