Best 48" (total length) gig bag

I've got a Mono bag but at 50" it's too big to fit in my car trunk (that's "boot" for you Brits).
My Zon bag, at 48", just fits. Since my bass is 34" scale I don't need the extra length of the Mono, but I sure like the protection and storage.

What are the best other options for a gig bag with max external length of 48"?

 

Bump

 

Thanks though.

 

Bump. Still no good answer...

 

Convertibles with big boots are hard to find!

 

The limiting factor is the size of the trunk opening plus width on one side. So I do angle it in to get it into the trunk. Trust me, I've worked all the angles on this. 48" gig bag just barely fits - I have to mush it a bit (which is wearing out my existing gig bag).
Convertibles with space for bass gear are rare beasts.
This is an Audi A4 convertible. It works, within the limit of a short gig bag.
Pre-2006 Jaguars have a big enough trunk space (I had one) but the maintenance is insane.
The newer Audi's (A3 and A5) trunks are too small. (Odd, the A5 is a bigger car with a smaller trunk).
BMW's - too small.
Camaro and Mustang - too small (I actually haven't checked the Camaro. But it isn't AWD like the Audi).
Miata? Beetle? Porsche? Mini? Don't make me laugh.
Mercedes? Too pricey. Same with Bentley. Big enough though...
