Yes but with a boot. I would say the cockpit is smaller than the long door cars.
Thank you - I'm tempted to get one for my daily commute - bang a hardtop on, and I reckon it'd be fine

I ran a Sprite mk 4 (Midget 3) for a year or two as my only car in 1980 and friends have a 1500 Midget.
They are comfortable as a daily driver and the hood is relatively weather tight - to the point where I would run it for a while before splashing cash on a hard top.
If the 1500 is the same crank arrangement as the 1300 Spitfire (it is the Triumph engine) - it has weak thrust bearings. A rattle on start up could mean a scrap block.
The rust potential is no different to any other BL car of the era - I suspect you know what to look for.
Apologies if any of this is teaching the elderly female relative to remove the contents of eggs.
