Thoughts on a 1998 E320 4-matic wagon?
 

My son is ready to retire his 2004 Saab 9-5 wagon to get rid of payments due to the price of gas. He is driving 150 round trip to work daily and the gas is killing him so even if he gets something that gets only slightly better mileage he will not have a monthly car payment. He likes wagons, has a 4 year old son and I am a long time MBZ owner. We have located a local 1 owner 1998 4-matic E320 wagon that we can by for cash $4000. It has 166k miles. Please any thoughts about this type car? mileage? dependibility with those miles, any known issues? thanks
