10 ft x-mas tree in my dad's Sebring while he was in Brasil. Needles everywhere but still better than the time we spread sangria in a 15 ft, 360 degree circle around my FiL's boat in 100 degree Texas summer. Looked like we had slaughtered a pig and would not come out. Try explaining that one...
Largest single object I've transported in the not-a-convertible Mazda.
On Saturday, however, the boot was full of beer, sneakers and other items you usually bring back from Estonia, and I then had the passenger compartment full of passengers and their stuff. I then drove 140km from Helsinki and the rear tires rubbed on the arches every time the road surface was uneven.
Damn it! Where the hell are my pictures of the miata in "going to the track mode." I knew I should have grabbed one yesterday. Picture a 90 red miata with the passenger side full of NT01, sleeping bag, and hammock, the trunk full of jack, tool bag, tool box, jack stands and helmet.
I haven't really carried that much in my convertibles. I've put a chair in the passenger seat, and I've loaded it up with tires many, many times. But none of these are truly a difficult fit. Being able to put the top down does help position the tires so they can be strapped in effectively.
Part of the reason my convertible hasn't had to carry as much on it is because it has a trailer hitch. I'll load up the trailer and the car and hit the road. It's carried a lot more than its supposed 500 pound (no trailer) capacity and handled it without issue. The brakes (at least with the tires I use) can take the extra weight. Acceleration is still better than the old Camry could offer. And handling... is fine, since a lot of the weight is on the trailer's suspension instead of the car's.
