4.9L V8 Engine. Excellent condition. 1991 Cadillac Eldorado Biarritz. Haggerty Motors values this antique car at $5000 in average condition. Priced to sell at $3200 or best offer! Front Seats and steering wheel have wear but have all matching covers. Small oil leak that does not effect driving, could use a tune up, and needs new connections for battery. Brand new battery and starter were out in writhing last year.
