i've got a k reg 1992 2.5 lwb , when i got it it only had 82000 on it.It's been very reliable and parts are easy to get hold of. Has for fuel its same as anything it depends how you drive it, i drive my with the rev counter, 3000rpm gives me 60-65 mph and in return about 30-35 to the gallon, but mine is manual i know autos are abit thursty.The only problem i have heard is head gaskets ,but if you find one thats been done you should be ok ,plenty of them about so have alook around i only gave £1600 for my
