For my 4/4 Sport I bought fitted bags from Hillsalive for behind the seats which are brilliant and adequate for most short trips (weekending). For longer trips I also bought a leather suitcase from motoring classics. This looks the part and comes with a fitted waterproof cover, and motoring classics being MG specialists, it's about half the price you'd expect from MMC. (Tho' I'm pretty sure the bag is made by the same people as the official Morgan one as I had a close look at the construction and fittings). For my money, the official morgan one was too big and too expensive.

It's still not light but a lot lighter than the MMC version.
