I'm 198cm 6'6" (?) and can fit in my GTV perfectly fine. Wouldn't want to be much taller though!
Size is irrelevant in a Spider since the top goes off most every day of the year - since we no longer have winters and showers - though heavy - never last for days.
And on those few occasions when it actually rains, just keep your head down
(with the hood up preferably)
.../... but I do garage it especially in wet weather. I've had no problems whatsoever but one thing to remember. If the weather is cold don't put hood down as it will crack the rear (plastic) window.../...
Mine lives outside all year around (I drive it nearly daily and I don't have a garage) and even with the original - 16 year old - hood: no leaks, no problems, fine isolation and with the small cabin it heats up really quickly in winter.
And whenever the temperature rises above 6 degrees or so, when the sun is out, down with the top and start grinning
.../... Spiders are great in the summer .../...
Spiders are ace all year around.
If you've never owned a ragtop, then now is the time!
(you can probably tell why I got the Spider, right?
