im trying to decide what to do with my disco, it needs a new engine block (heads are fine) i was going to leave it till i can afford an engine or block but if it was worth much selling it for spares or repair i might advertise it, its a 1999 d2 v8 98k miles, 5 seats, rear air suspension, ace and it had 4 new pirrelli atr put on last year, any ideas what its worth
