Paint Year
1998
Interior Notes
Due for an extensive interior refurbishment; headliner is okay, but new plastics, carpet, seat covers, side panels etc. all due for replacement/refurbishment.
Exterior Notes
Due for a good paintjob, for ramp appeal. Paint was redone in 10/1998 as well, along with new windshields.
