AI market analysis

For buyers

Be wary of the $99,500 eBay asking median, which significantly overshoots the realistic $60,000-$70,000 grey market transaction range. Target offers between $68,000-$75,000, emphasizing that actual sales at or above $80,000 are rare given the low liquidity. Patience is key to securing a deal closer to the true market value.

For sellers

Recognize that the $99,500 eBay asking median is likely inflated, contributing to low liquidity for actual sales. To move this 2011 Aquanaut Travel Time efficiently, target a realistic asking price between $78,000-$88,000. Ensure your listing prominently features a full set (box and papers) and recent service history to justify this premium above the $60,000-$70,000 grey market transactional range.
