1973 Mercury Cougar XR7 convertible This was the last full-size convertible available from Mercury, and it was considered both luxurious and sporty. Best of all, an owner can still do his or her own maintenance on these cars in many cases. In 1973, there was still a choice of engine size up to a big "429." Current KBB Early Model Value, in good to excellent condition with base engine: $13,200 to $26,300.
