Hi all! Im new to this site and joined because Im considering the purchase of a 2001 deville....car has 86k for mileage & looks good, seems to run good but has the abs light on, the service engine soon light on and the traction control light is on, if I push the switch, nothing happens ....the other things I see/feel/smell is possibly a bad engine or trans mount(are these common to go bad?) sometimes when I gas it it seems to make a thud feeling....the other thing is a slight smell of antifreeze under the hood...I cant see it leaking on the ground but do smell it. My questions are, what could the lights on the dash be? What problems do these cars most normaly encounter?? What should I look for or be aware of before I buy it?? thanks for all the advice!!
