The list price for an Ibanez Mikro bass is $299. We can agree that adding branded replacement pickups & selling it for this price is a difficult proposition considering this amount of money can get us a, new bass.
The RG1527 was in the Prestige line up replacing the RG7620 in the early 2000s. It was a respectable guitar but it was listed for $1.7K +/- so the price you see here reflects the custom paint finish + Fishman pickups. Worth the extra $$$? That's your call.
According to the seller, the cracks there is a factory defect. By the looks of it, since it went round the heel, it might be the result of a fall causing stress cracks on that area. It's gonna be a costly repair...
