A credible top-ten ranking of vintage tourist cars should weigh more than headline auction prices. Guide values offer a useful baseline, while completed sales show what buyers actually paid. I would compare both, then adjust for condition, originality, documented history, and sale date.
Markets move. Fast.
The strongest candidates tend to include prewar open tourers, postwar two-seat roadsters, elegant four-seat convertibles, and roomy grand touring cars. Their appeal is easy to picture: folded canvas roofs, narrow windscreens, and enough luggage space for a weekend trip.
Yet “tourist car” can describe very different vehicles, so comparing them directly is imperfect. A restored example may sell far above a tired project, even when both share the same model name.
Auction results also vary by country, currency, and buyer fees. I would therefore present estimated value ranges, cite the number and dates of comparable sales, and mark uncertain rankings clearly. A single record price makes a poor guide. The final order should reward strong market evidence, not just beautiful photographs.
