Classic convertible sports car auctions: all marques, searched at once

Classic convertibles, from a 2000s Mercedes CLK to a 1990s Jaguar XK8, turn up regularly through specialist car auction houses and general estate sales alike, and mileage, service history and soft-top condition all factor heavily into value alongside the marque and model itself.

Why classic convertible lots get missed

Car auction houses list hundreds of lots per sale, and a genuinely good convertible can be scheduled for a sale you never think to check, while a general seller might undersell one without highlighting its condition or history properly.

One search across every platform

Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay. Search a marque like "Mercedes convertible" or "Jaguar XK8," "classic convertible," or "cabriolet" generally and results return across all of them, with images, estimates, current bids where shown, and sale countdowns, sorted by platform in tabs.

Real results for "classic convertible sports car": a genuine Mercedes CLK 200 and Jaguar XK8 convertible, found in one search across car auction houses.

It works by searching from inside your own browser, the same as opening and searching each site yourself, just done in seconds. Nothing is stored on our servers, permissions are minimal, and the extension never places a bid on your behalf.

Alerts: essential in a fast-moving market

A genuinely good convertible rarely stays listed for long once collectors notice it, so save a search (a marque, model, or "classic convertible" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay, rather than relying on remembering to check each one.

Want to try before installing?

The same search box works on this website with no install at all for eBay, iCollector, LiveAuctionWorld and Featured Auction catalogues, a quick way to see matching convertible lots before adding the rest of the platforms via the extension.

Built for how classic car buyers actually work

Save any lot with one click from search results, export your shortlist as a printable PDF or CSV before a sale, and on the day itself the optional live bridge feeds the auctioneer's asking price into the free bid calculator, so your maximum (with buyer's premium and VAT included, plus a reminder to check transport costs) is always in front of you.
