I purchased my 2009 vw Eos from a dealeriship "as-is" and I have had to replace the maf sensor, throttlebody had to be serviced with in the first year of owning. Oil leaking from engine onto the water pump. Now, the abs and traction electrical system is completely messed up and I can't drive it. Estimation of $2500 worth of work.
