ZR2 Advice.

Hi I'm new here. And I've been thinking of buying a used ZR2 mid/ late 90's. I'm looking for any owners out there who can give me advice on problem areas to look out for? What can I expect for gas mileage? I have an older Ford Explorer and the repairs are geting a little to much. It does ride good and has plenty of room inside. I like it but it's time for it to go!
