sounds like it might be burning some oil, with 240K miles it doesnt surprise me. sounds like the majority of those miles are highway. but i wouldnt pay more then $1200....
1998's all had the KA24DE, did they not? It is a 4 cyl, either way.doesn't sound bad to me... 1/2 quart is nothing... my 95 taco burned that by every 3k oil change at over 200k/mi... and i sold it for $5k with 250k/mi... and yes toyotas hold their value like crazy, but you pay a lot more upfront too so it kind of washes out... is the 4X4 a V6? cuz from what I hear they won't get the crazy high mileage like you get with the I4
