Very small
This wasn't even big enough for my two-door Honda civic...it's more for a mini than a compact! Not a good fit.

Polypro Car Cover
This car cover is light weight, inexpensive and protects the car finish of dust and bugs. I purchased the mid-size and it is a bit bigger than needed for my Jetta.
It would be good information if the company would state the size or give examples of the car models that the sizes fit.
At any rate, I feel that this is a good cover that protects the car finish from the environment.

decent fit, but hard to pack away, could use more straps
This cover fits reasonably well, but is hard to pack away, and lets the wind blow dust up under the sides.

The attached carry-bag goes in the trunk and anchors the cover, and there's a small cord that is meant to pass under the car and through two grommeted holes on each side of the cover to keep it from flapping.

I tried it on both a Honda Civic (2006) and a Plymouth Avenger. On the Avenger (mid/full-sized car), the cover didn't reach the bottom of the car on the sides, but fit fine elsewhere. Perhaps because of that, I had wind blow dust/dirt up inside the cover.

Like most large items with a "convenient carrying case", actually folding the item into a semblance of its original configuration to put it back in the bag is a challenge (especially on a cover that has no real corners because of its elastic edging -- it's like folding a very large fitted sheet). There really should be markings on the cover to make this easier ("fold here").

For the price, this is a decent cover, though not perfect.

DOESN'T FIT MUSTANGS
I bought it for my one-of-a-kind custom mustang AND IT DOESN'T EVEN FIT.

Mustangs aren't that large of a vehicle so what the heck

Car cover
I received the cover promptly after ordering. Overall, I'm satisfied with the purchase. I like the material of the car cover and it is doing what I need it to do. Note: While the mid size fits well front-to-back, the sides could be a bit longer for a 2009 Corolla.
