Stop it! Smells like fuel. Rattles your body. Loud as heck. Fits like a glove. Wife doesn't want to go. I really want one now!Although this is at least 'inferred' in Tony's comments above, it probably should be stated directly:
Anyone who might be even slightly claustrophobic (or has a spouse who is and 'said spouse usually accompanies you) would be well advised to sit in a GT40 with its doors closed before even beginning to look for one to buy. A GT40 truly IS a car that's "worn" - occupants do not just simply sit "in" one. The expression ("You do not sit in a GT40 - you wear it") is darned close to being a 100% literal fact.
Wifey was not at all 'comfy' in the MKII we sat in...she couldn't get out of it quick enough once the doors were closed.
